Subject: [PATCH 001/656] Cache extruder settings.

When writing GCode, there are certain settings that need to be checked
over and over again. Instead of pulling them from the Settings hash
table every time, read them once and then save them. This speeds up
single-threaded slicing by about 3% (one thread of a 5950X; with
many threads, it seems to be more like 10%, since GCode writing
then takes proportionally more of the time).

There is a very large long tail of code that keeps reading these
settings, in particular from mesh settings, so there is probably
more to be gained here, but this patch takes out the two biggest cases.

Subject: [PATCH 024/656] Rework converters into separeted (send,receive)
 concepted closures.

Work in progress! Just adjusted the types.h, the rest of the code has been changed underneath of me anyway (since we now have about 3 to 4 devs on the same piece of code) -- Need to make it work afterwards.

This change, if it works properly, should simplify everything, since you only need to specify two 'loose' functions that get typechecked properly by the concepting.

Subject: [PATCH 030/656] Reworked converters

The used proto types are needed in the slotproxy
instead of sending that type info twice, the simple closures
had to be replaced with a slightly heavier one.

- Placed converters in their own header
- Use structs
- Update slotproxy to use these converters

Subject: [PATCH 039/656] Throw on validator and communication errors

Validator:

Added a member variable semver_range_ to store the version range
Moved the version_range_ member variable to semver_range_
Added a valid_version() function to check if the version satisfies the range
Added a getVersion() function to retrieve the version as a string
SlotProxy:

Added an #include directive for <exception>
Added exception handling for plugin validation and communication errors
Throws a std::runtime_error if the plugin version is invalid or cannot be validated
Throws a std::runtime_error if communication with the plugin fails
Improved log messages for plugin responses
These changes improve the error handling and validation in the SlotProxy class.

Subject: [PATCH 040/656] Allow for default behaviour if no plugin is used

This commit updates the plugin registration in the Application class in the Application.cpp file. The changes include:

Adding support for default functions in the simplify_slot and postprocess_slot classes.
Creating a slot_registry typedef to hold the slots for simplification and post-processing.
Conditionally registering the simplify_slot based on whether the front-end starts a plugin.
Registering the postprocess_slot unconditionally.
Demonstrating the usage of the simplify_slot by invoking it with sample data.
These changes allow for flexible plugin registration and usage in the application.

Note: Further modifications may be required based on the specific requirements and configuration of the application.

Subject: [PATCH 041/656] Use curaengine_grpc_definitions conan package

[plugin.proto] Remove plugin.proto and related definitions

This commit removes the plugin.proto file and its related definitions. The file contained definitions for plugin identification and validation, as well as messages and services for the SIMPLIFY and POSTPROCESS slots. These definitions are no longer needed and can be removed from the codebase.

[conanfile.py] Add dependency on curaengine_grpc_definitions

This commit adds a new dependency on the curaengine_grpc_definitions package. The package provides the latest gRPC definitions for CuraEngine plugins. This dependency is necessary for proper integration with the plugin system and ensures that the correct gRPC definitions are available during the build process.

[include/plugins/slots.h] Update gRPC include paths

This commit updates the include paths for gRPC headers in the slots.h file. It replaces the previous inclusion of "plugin.grpc.pb.h" with "simplify.grpc.pb.h" and "postprocess.grpc.pb.h". This change reflects the updated structure of the gRPC definitions and ensures that the correct headers are included for the SIMPLIFY and POSTPROCESS slots.

[include/plugins/converters.h] Update gRPC include paths

This commit updates the include paths for gRPC headers in the converters.h file. It replaces the previous inclusion of "plugin.grpc.pb.h" with "simplify.grpc.pb.h" and "postprocess.grpc.pb.h". This change reflects the updated structure of the gRPC definitions and ensures that the correct headers are included for the SIMPLIFY and POSTPROCESS slots.

[CMakeLists.txt] Update gRPC protos variable

This commit updates the GRPC_PROTOS variable in CMakeLists.txt. The variable now contains a list of all gRPC definitions provided by the curaengine_grpc_definitions package. The list is used during the build process to generate the necessary code for gRPC services and messages. The updated variable ensures that all required gRPC definitions are included in the build.

Subject: [PATCH 042/656] Move pluginproxy to seperate header

include/utils/concepts/generic.h:

The concept definition hashable is updated to use the std::convertible_to concept instead of concepts::convertible_to which likely caused a compilation error.
include/plugins/slots.h:

Unused includes for range/v3 and simplify.grpc.pb.h are removed.
The commented-out code block related to details::process_default is removed.
A comment mentioning the removal of the need for implementation headers is added as a TODO reminder.
Some formatting changes are made for code readability.
include/plugins/slotproxy.h:

The unnecessary include guards and includes for <exception>, <optional>, <agrpc/asio_grpc.hpp>, <agrpc/grpc_context.hpp>, <boost/asio/awaitable.hpp>, <boost/asio/co_spawn.hpp>, <boost/asio/detached.hpp>, <fmt/format.h>, <grpcpp/client_context.h>, <range/v3/utility/semiregular_box.hpp>, and <spdlog/spdlog.h> are removed.
The unused plugin.grpc.pb.h include is removed.
Formatting changes are made for code readability.
src/Application.cpp:

The missing include <grpcpp/create_channel.h> is added to fix a compilation error related to creating a gRPC channel.
No other changes were made in this file.

Subject: [PATCH 043/656] Refactor plugin-related code and update includes

This commit makes several changes to the plugin-related code:

1. include/plugins/pluginproxy.h:
   - Updated the template parameters of the PluginProxy class to use grpc_convertable for Request and Response types.
   - This change ensures compatibility with gRPC conversion requirements.

2. include/utils/concepts/generic.h:
   - Renamed the include guard to UTILS_CONCEPTS_GENERIC_H to match the file name.
   - Updated the concept grpc_convertable to handle gRPC-specific conversion requirements.

3. include/plugins/slotproxy.h:
   - Added the <concepts> include to use concepts in the code.
   - Updated the template parameters of the SlotProxy class to use grpc_convertable for Request and Response types.
   - This change ensures compatibility with gRPC conversion requirements.

4. include/plugins/converters.h:
   - Reordered the include statements for clarity.
   - Removed the unnecessary include for postprocess.grpc.pb.h.

These changes aim to improve code clarity, ensure compatibility with gRPC conversion requirements, and update includes for consistency and readability.

Subject: [PATCH 044/656] Prerequisites for secure validator.

Have secure communication when enterprise compile flag is set. The engine and plugins will both be started with the same shibolet, a plugin will then hash this with an openly avialable public key, so the engine can check that with the private key. It's assumed that the key-pair will only have to change when there has been a security violation.

Subject: [PATCH 050/656] Fixed anonymous namespaces in multiple translation
 units

- Add default_process struct to slots.h
- Change Default template parameter from auto to class in slots.h and slotproxy.h
- Add default_process member to SlotProxy
- Remove unused code in Application.cpp

Parsing anonymous lambda's in the header,
results in different slots registry types in
different translation units. Which is kinda
bad if it is a Singleton ;-)

Subject: [PATCH 053/656] Added some benchmarking for the plugins and slots

I ported the simplification algorithm to the plugin https://github.com/Ultimaker/curaengine_example_plugin with some small modifications to make it work with vectors of containers instead of our Polygons.
and I wrote three different Benchmarks, guess which scenario was the best:

1st scenario = is our current simplify logic
2nd scenario = a plugin slot, which will default to the current simplify logic (scenario 1), because there is no plugin loaded.
3th scenario = a plugin slot, with the example plugin loaded.
All scenarios would result in the same simplification, but it is a good indication that the slots/plugin logic as it is now seems to have minimum overhead. It is even quicker by a whooping 1.5 nanosecond :wink:

Subject: [PATCH 060/656] Allow Cura front-end to set plugins (port & address)

This can currently be done by setting the environment variables:
- SIMPLIFY_ENABLE: default disabled, setting this to any value will enable the plugin
- SIMPLIFY_ADDRESS: defaults to localhost
- SIMPLIFY_PORT: defaults to 33700
- POSTPROCESS_ENABLE: default disabled, setting this to any value will enable the plugin
- POSTPROCESS_ADDRESS: defaults to localhost
- POSTPROCESS_PORT: defaults to 33701

Subject: [PATCH 065/656] Update protobuf and grpc files

This commit updates the protobuf and grpc files to reflect the changes made on the arcus_replacement branch of the CuraEngine_grpc_definitions repository. The changes were necessary to ensure compatibility and consistency with the updated definitions.

This branch now uses the by @casperlamboo proposed new Protobuf types, but modified, such
that we can start pulling out libArcus and pyArcus.

Codebase consistency: The modifications made in this commit ensure that the protobuf and grpc files used in the current branch align with the definitions present in the arcus_replacement branch of the CuraEngine_grpc_definitions repository.

Subject: [PATCH 067/656] Fix variant storage in array, using typelist

This commit updates the include/plugins/slots.h file, making several changes and improvements.

Added #include <exception> to include the necessary header.
Removed the unnecessary utils/Simplify.h inclusion, with a comment to remove it once the simplify slot has been removed.
Added utils/IntPoint.h inclusion for future use.
Refactored the default_process struct's operator() for better code readability.
Updated the simplify_default struct's definition.
Refactored the simplify_slot and postprocess_slot aliases for better readability.
Added the Typelist and Registry template classes for managing plugin slots.
Added the SingletonRegistry template struct for ensuring a singleton instance of the registry.
Updated the simplify_t and postprocess_t aliases to use the new registry classes.
These changes improve the code structure, organization, and maintainability of the plugin slot management system in the Cura software."

Subject: [PATCH 068/656] Update the validator

This commit modifies the include/plugins/validator.h file, introducing improvements and enhancements to the validator class used in plugin validation.

Added the <fmt/format.h> header for improved formatting capabilities.
Rearranged the header includes for better organization.
Modified the Validator class constructor to handle invalid formatted versions gracefully, providing an informative error message.
Updated the valid_version() function to provide a more detailed error message when the version is not within the required range.
Added a what() member function to retrieve the error message associated with an invalid version.
Improved code readability and added appropriate comments.

Subject: [PATCH 069/656] Update Slot/Plugin proxies to work with new
 exceptions

This commit updates the pluginproxy.h and slotproxy.h header files with the following changes:

In pluginproxy.h:

Added necessary #include statements and dependencies.
Introduced member variables to store plugin information.
Modified the constructor to include plugin initialization and validation logic.
Modified the operator() function to include plugin execution and error handling.
In slotproxy.h:

Added a required #include statement.
Modified the constructor and operator() function to handle plugin availability and error handling.
These changes enhance the functionality and error handling of the proxy classes for plugins.

Subject: [PATCH 071/656] Fixed the connect functionality

In the file include/plugins/pluginproxy.h:

Added the ranges::semiregular_box<stub_t> member variable stub_ to the PluginProxy class.
Removed the plugin_ready_ member variable.
In the file src/communication/ArcusCommunication.cpp:

Uncommented the lines that connect the simplify and postprocess plugins.
In the file include/plugins/slotproxy.h:

Replaced the std::optional<PluginProxy<...>> member variable plugin_ with value_type.
Updated the constructors and assignment operators accordingly.
In the file src/slicer.cpp:

Removed the TODO comment and unnecessary code related to invoking the simplify_slot plugin.
In the file include/plugins/slots.h:

Updated the version requirements in the simplify_slot and postprocess_slot aliases.
In the SingletonRegistry class:

Added a connect member function to connect a plugin to a slot.

Subject: [PATCH 078/656] Refactored plugins and slots

This commit refactors the PluginProxy class and converters.h in the include/plugins directory. It introduces validation for plugin requests and responses and handles communication failures. The changes include:

Refactored PluginProxy class: The PluginProxy class has been modified to use template parameters for RPC_ID, SlotVersionRng, Stub, ValidatorTp, RequestTp, and ResponseTp. It also uses aliases for easy use of types.
Updated request and response converters: The request and response converters have been updated to use the new types.
Added validation and communication failure handling: The PluginProxy class now performs validation on plugin requests and responses. It also handles communication failures and throws appropriate exceptions.
These changes improve the functionality and reliability of the PluginProxy class and ensure proper validation and error handling during communication with plugins.

Subject: [PATCH 102/656] The squared dist-to-line should give the same answer
 as plain.

Quick fix for now, as it's not much slower. Also disable the test for the line-segment version, since I'm not sure it should _always_ give the same answer here, and it's not relevant to the simplify problem.

Subject: [PATCH 103/656] Simplify: Iterate until it doesn't change anymore.

Simplify should be idempotent if the polygon already meets the criterea. Simplifying again shouldn't yield new results. The old version could do that, both in the sense that the by_importance vector wasn't completely exhausted, which could happen if if the poly[gon|line] was still larger than [3|2], since not every remove call removed a polygon. But also in the sense that iteration made it remove more in some cases. As these cases are not _that_ common, will only simplify the already simplified polygon, and simplification in and of itself can give speed boosts in the other part of the code (as well as the fact that this can't loop forever, sicne at some point there has to be an iteration where nothing is removed anymore), I think this is acceptable, at least for now.

Otherwise this can introduce microsegments, which is bad. With nominal vailues, the current minimum is still usually smaller than the typical nozzle aperature, so a large regression in other areas is not expected. Don't set it to the full max-resolution length though!

Subject: [PATCH 112/656] Disable Small Skin Area feature for now :-/

We're not sure why this introduces a boatload of small segments into the infill, and we're out of time to try and fix this before the beta. Re-introducing after the beta seems like a bad idea, so this'll have to wait until 5.5 unfortunately.

Done as part of fixing for CURA-10500, but for the original Small Skin Area feature, see CURA-10201. For the ticket to (fix? and) reintroduce the feature, see CURA-10670.

Add a smooth action, which will smooth small segments (maximum resolution) of a polygon,
whom deviate more than a certain angle (wall transition angle) compared to a fluid motion
line between the segment before and after.

Smoothing is done by moving the first point of the small middle segment to the first point
of the previous point with a smooth distance (need to add this to the front end).
The second point of the middle segment is moved to the second point of the last segment.
If either the previous or next segment is shorter then the smooth distance, then that point
in the middle segment is removed

Subject: [PATCH 124/656] Allow uniform coordinate query with std::get

This would allow for getting a x,y,z coordinate for a IntPoint, or 3D point,
described as a struct or vector/array/tuple etc. Will be expanded to accommodate
Arachne types.

```
struct Point{ int X; int Y; }
Point p_struct{ .X = 1, .Y = 2. };

std::array<int, 2> p_array { 1, 2 };

auto x_struct = std::get<"X">(p_struct);
auto x_array = std::get<"X">(p_array);
```

Subject: [PATCH 129/656] Refactor smooth action and fix pointer issues

Update smooth action to handle changing path size, cycle views, and filtering out removed points. The previous implementation had issues with sliding views due to the path size change. Also, fix range constraints and improve readability.

This refactor improves the algorithm's accuracy and performance by better handling the changing path size and filtering out points marked for removal. Additionally, the updated range constraints and readability make it easier to understand and maintain the code.

Subject: [PATCH 130/656] Refactor smooth action in utils codebase

The `smooth` action codebase has been heavily refactored to improve
readability, avoid redundancy and make the codebase more efficient.
Importantly, third-party library RangeV3 has been more efficiently used,
unnecessary headers were removed, and unnecessary debug logs were
deleted. Also, reusable shifting operation for p1 (towards p0) and p2
(towards p3) were extracted to a new function, `shiftPointTowards`.

Subject: [PATCH 131/656] Optimize smoothing function and fix error in
 shift_points

The smoothing function has been optimized and a bug with the
shift_points function has been fixed. The operator in the smoothing
function has been made "constexpr" to potentially improve performance.
The way "windows" are generated has been restructured to make it clearer
and eliminate redundancy. In shift_points, the subtraction used to alter
point's coordinates was replaced with addition to rectify a mistake. The
distance calculation in the smoothing function has been adjusted from an
incorrect dot product into a correct hypotenuse calculation. These
changes should help in improving the efficiency and correctness of the
smoothing function.

Subject: [PATCH 132/656] Refactor SmoothTest for more reliable results

The existing tests for the smooth function were simplified and adjusted.
It applies the smoothing function to those points and then verifies that
the original polygon remains the same after smoothing. This change will
make the test more reliable as it verifies that smoothing algorithm
doesn't alter essential data.

Subject: [PATCH 134/656] Extended geometrical type concepts

This commit adds more granular checks for geometrical types (2D & 3D
points) in the geometry header. It introduces concepts to inspect
whether types are represented as tuple, range, or named fields.
Moreover, it checks if an object is of type segment or a range of
segments. This refactoring enhances versatility for geometrical types,
ensuring greater type safety and readability in the code.

Subject: [PATCH 135/656] Add functionality to access 2D and 3D point
 coordinates by index or character

This commit addresses the need of accessing point coordinates more
flexibly. It introduces functions to access the coordinates of 2D and 3D
points either by coordinate index (e.g. 0 for X, 1 for Y in a 2D point)
or by character (e.g. 'x' or 'X' for X-coordinate). It makes handling
points more intuitive and comes in handy when the specific type of point
(2D or 3D) is not of interest. Additionally, accessing coordinates of a
junction by index or character is also implemented, further enhancing
the ease of use.

Subject: [PATCH 136/656] Update comment syntax in geometry.h

In this commit, the syntax for the comments in the geometry.h file has
been updated. The "\\" syntax was replaced by "@" as the latter is more
standard for Doxygen usage. This change allows for better parsing and
generation of documentation by Doxygen, and aligns with common practices
in the software industry.

Subject: [PATCH 137/656] Refactor smoothing function, remove unused parameter
 and improve readability

The smoothing function in `smooth.h` was refactored to improve code
readability and maintainability. The 'smooth_distance' parameter was
removed as it was not being utilized. The core logic of the function
remains unchanged, and several variable names were updated to better
reflect their context and function. Introduced a clearer, more accurate
method to calculate the cosine of the angle deviation which is also
generally optimized for smaller values of the `fluid_angle`. This is a
more computational efficient approach since for 'Curved' interpolations,
the `fluid_angle` is usually small which solves the primary problem.

Subject: [PATCH 138/656] Refactor smoother functionality in WallToolPaths

Moved the 'smoother' logic from the 'slicer' and 'WallToolPaths'
execution to occur earlier in the 'prepared_outline' execution. This
change intentional to reduce redundancy and improve the efficiency of
our slicing process by ensuring we're smoothing the polygons just once.
This could also help reduce the amount of crashes in the Voronoi
generation/usage

An unnecessary smoother function call with redundant parameters was also
removed from src/slicer.cpp."

Subject: [PATCH 139/656] Refine path smoothing algorithm

Updated the path smoothing algorithm by refining the condition checks
and optimizing certain calculations for better efficiency.

- Introduced a condition to handle open paths.
- Corrections in comments for better understanding.
- Loop stop condition refined to prevent unwanted iterations.
- Compute function introduced to calculate magnitudes, making the code
   cleaner.
- Reorganized functions for better readability.
- Deviation calculation and filtering methods optimized for better
   performance.

This update is aimed at enhancing the performance of path smoothing.

Subject: [PATCH 140/656] Update smoothing parameters in test

Updated the parameters in the SmoothTest of CURA utility tests.
The third parameter of the smoothing function has been removed due to
recent changes in the CURA engine algorithm. Consequently, the expected
results of test were also updated to match the output from the updated
smoothing function.

Subject: [PATCH 143/656] Update Geometry checks for compiler support of
 std::integral

Due to varying support for the C++20 feature std::integral, preprocessor
checks were added to the Geometry utility. This ensures that the
Geometry utility functions will compile and run as expected across
different compilers, especially older ones or those that don't fully
support C++20 yet. Additionally, if std::integral is not supported,
standard member accessing is used instead. This modification enhances
the code's robustness and compatibility.

Subject: [PATCH 145/656] Adjust Arachne type checks for different C++ versions

This commit addresses potential compatibility issues with different
versions of C++ by adding conditionals to the `junction` concept in the
`arachne.h` utility file. As some versions may not support the
`std::integral` check, we fall back to directly assessing `val.w` if
the C++ version is older or a particular library version with
compatibility issues is detected. This change ensures successful
compilation across varying environments.

Subject: [PATCH 146/656] Refactor std::integral usage for C++ compatibility

This commit removes the preprocessor conditions that were originally put
in to cope with an issue in Clang13 C++20. A fallback version of the
integral concept has been added in the std namespace if the C++ version
is below 201703L or if the library version is lesser than the Clang13
version. This allows for a cleaner and more compatible codebase across
various C++ versions. In addition, "include/utils/types/generic.h" is
now being included in "include/utils/types/geometry.h",
"include/utils/types/arachne.h" and "include/utils/actions/smooth.h"
everywhere std::integral might be used.

Subject: [PATCH 149/656] Refactor angle checking in smoothing utility

The angle checking in the smoothing utility now check against actual
angles instead of the cosine angle. This is slightly more computational
heavy but needed since otherwise a lot of points where missed.
The function `isWithinDeviations` has also been renamed to
`isWithinAllowedDeviations` for clarity.

Subject: [PATCH 150/656] Start the window at the tail

Often the first segments weren't filtered, by concatenating the tail to
the front we also take these last elements into account.
Also, adjusted the conditions in if-statements for better accuracy and
introduced variables for allowed deviations and smoothing distance for
better code consistency.

Subject: [PATCH 153/656] Replace 'tail' with 'single' in smoothing process

This change replaces the 'tail' view with a 'single' view in the
smoothing process of the model. The change ensures that the smoothing
process takes into consideration the entire model, instead of ignoring
the first point (head). The 'single' view denotes the single element at
the back of the range 'tmp'. This small adjustment ensures the smoother
start of the 3D model's path and addresses a specific corner case where
the first point was being neglected.

The filter condition has been altered to be less aggressive, since the
intend is to smooth out the small sudden deviations. With this in mind
the removal of points is also discarded since this can introduce self-
intersecting shapes, which will result in hard crashes, but more
importantly introduce to much of a deviation from the intended shape.

Subject: [PATCH 156/656] Reorder includes and add logging in
 SkeletalTrapezoidation

This commit reorders the includes in SkeletonTrapezoidation.cpp for
better code organization and adds a logging line to aid troubleshooting.
 The logger will now print values of polys, section_type, and layer_idx
 when constructing from polygons, giving better visibility into their
 state in case of issues.

Subject: [PATCH 157/656] Skip smoothing for support walls

Added condition to skip smoothing process for sections that are of
section type 'support'. This is done to improve performance and
eliminate unnecessary computation as these support walls do not require
smoothing.

Subject: [PATCH 165/656] Improve code readability and add assertions

Applied review comments.

This commit addresses several changes in the code to improve readability
and add more assertions where necessary. Redundant comments have been
removed, such as the namespace declaration in geometry.h for
readability. Grammar mistakes in comments were corrected for the same
reason in smooth.h.

In get.h and generic.h, a static assertion was added to restrict the
size of the string value to one character, ensuring concise point
coordinate inputs. In generic.h, a comment was added to indicate why we
are adding a manual implementation of integral and floating point, due
to lack of support in older versions of Apple Clang.

These changes were made to improve the quality and maintainability of
the code.

Subject: [PATCH 171/656] Move generic.h to types folder and add
 grpc_convertable concept

The file generic.h was moved from the utils/concepts directory to the
utils/types directory to better reflect the contents of the file, now
including a new concept for grpc_convertable. This new concept checks if
a type T is a semiregular type that can convert to grpc. This enhances
the code's clarity and can improve the development of grpc-utilizing
functionalities.

Removed "RETARDED_APPLE_CLANG" option and replaced it with
"OLDER_APPLE_CLANG". This change was made to give a clear understanding
of the option's function, which is to check if the Apple Clang version
used is 13 or older.

Subject: [PATCH 173/656] Shift UUID generation from FffGcodeWriter to
 Application

The changes are intended to centralize UUID generation inside the
Application class rather than in each instance of the FffGcodeWriter
class. This approach allows plugins to hook up with multiple instances
and still differentiate where the data comes from.
This is done by introducing instance_uuid data member in the Application
class which generates and stores UUID. This UUID is then used in
 FffGcodeWriter constructor. This change also removes the dependency on
  boost/uuid in FffGcodeWriter.

Subject: [PATCH 174/656] Add `engine_uuid` and `thread_uuid` to metadata

Changed `instance_uuid` from `std::string_view` to `std::string` in
`Application.h` and added `engine_uuid` to `metadata.h`. Also included
`<thread>` and `Application.h` in `pluginproxy.h` to generate
`engine_uuid` and `thread_id` for every thread and added these keys to
metadata for the RPC's such that plugins can keep the books
where data came from.

Updated the 'curaengine_grpc_definitions' version to use the latest from
'ultimaker/cura_10714' instead of 'ultimaker/testing' in conanfile.py.
This change ensures our project is using the grpc definitions
with the handshake RPCs added to the services

This commit updates the gRPC method naming in Slots and Converters files
from 'Modify' to 'Call' based on recent API changes. In the PluginProxy
file, a function to prepare the gRPC client context has been extracted
for reducing code repetition and improving readability.

Subject: [PATCH 182/656] Handshake RPC during plugin creation

Implement Handshake RPC during plugin creation

A handshake mechanism has been added during plugin creation, ensuring
the necessary compatibility and functionality verification before
initializing the plugin. This change refactored the PluginProxy class
to establish the handshake during the plugin construction and validate
it. Adjustments to plugin_metadata structure and exception handling were
also necessary. The handshake message conversion logic has been added
with simplify_request and handshake_response structures.

This action was necessary to ensure the appropriate plugin version is
used, improving system reliability and stability.

Subject: [PATCH 183/656] Refactored co_spawn lambda in pluginproxy.h

Refactored the lambda function present in co_spawn calls located in
methods of pluginproxy.h. This change intends to increase readability
and maintenance. The lambda implementation was moved into private member
functions 'handshakeCall' and 'modifyCall'. This enhances code
organization allowing for easy modification and reuse in the future.

Subject: [PATCH 184/656] Moved private members in pluginproxy.h

This refactoring aims to make the public API more clear and
understandable by moving private members to the bottom of the file. With
this change, it will be easier for the developers to identify and
understand the public methods and attributes of the class at a first
glance, improving the maintainability and readability of the code.

Subject: [PATCH 193/656] Add the plumbing for the Broadcast functionality

This commit introduces the broadcasting capability within plugins.
The `broadcast` method was added in slots.h, slotproxy.h and
pluginproxy.h files.
This enables broadcasting of a message across multiple channels,
improving the communication aspects within the plugins. Along with this,
 some changes in the imports were made allowing a better organization of
  used modules.

Subject: [PATCH 194/656] Add Broadcasting logic

A broadcast can now be made for a specific RPC.
Overloading of the different Broadcast RPCs is
done in the Broadcast header.
Where a `broadcast_message_factory` and `broadcast_factory`
need to be created for each RPC.

Subject: [PATCH 198/656] Better error handling on miscommunications

In the previous implementation, there were potential issues in handling
 errors especially when an external service miscommunicated with the
 plugin. This update includes the plugin_info in the handshakeCall
 function to address this flaw. Now, in case the service fails to
 respond properly, the system will provide meaningful error messages and
 help the user understand the source of the problem.

Subject: [PATCH 204/656] Plugin-system: Complete renames/moves
 (details->utils,x_MODIFY)

'Got it working on Windows' -- except that it wouldn't have worked on other systems probably if a complete recompile was done ;-)

part of epic CURA-10560 (originally done for CURA-10715, but in one of the CURA-10618 branches -- look it all made sense at the time, ok?)

Subject: [PATCH 205/656] Force wait on handshake result

If this isn't performed in the context of the initializer.
The plugin will not be validated and the Broadcast won't
be subscribed to before it actual usage.

Subject: [PATCH 221/656] Update clang-formatting rules

Changed multiple rules in .clang-format for better readability and
up-to-date standard usage. Primarily, alignment rules were adjusted,
binary operators now break before all, column limit was reduced for
tighter code blocks, and the c++ standard was updated to c++20. These
amendments sought to improve overall code legibility and ensure
adherence to modern c++ standards.

Subject: [PATCH 222/656] Don't format concepts (yet)

Our current used clang-format (14) doesn't have full support for it yet
since 14 is the current standard on Ubuntu and on our GH runners added
`clang-format off/on` guards around those code blocks.

-                                 watertight, there will be adjacent triangles on all 3 sides that
-                                 are not flat on the layer.
-                               - If two of the vertices are exactly on the layer, only count the
-                                 triangle if the last vertex is going up. We can't count both
-                                 upwards and downwards triangles here, because if the model is
-                                 manifold there will always be an adjacent triangle that is going
-                                 the other way and you'd get double edges. You would also get one
-                                 layer too many if the total model height is an exact multiple of
-                                 the layer thickness. Between going up and going down, we need to
-                                 choose the triangles going up, because otherwise the first layer
-                                 of where the model starts will be empty and the model will float
-                                 in mid-air. We'd much rather let the last layer be empty in that
-                                 case.
-                               - If only one of the vertices is exactly on the layer, the
-                                 intersection between the triangle and the plane would be a point.
-                                 We can't print points and with a manifold model there would be
-                                 line segments adjacent to the point on both sides anyway, so we
-                                 need to discard this 0-length line segment then.

Broadcasting in plugins has been refactored to use
`v0::SlotID` instead of `utils::CharRangeLiteral BroadcastChannel`.
This provides better clarity and consistency across the system.
A new dedicated broadcast slot, `slot_settings_broadcast`, has also been
 added for dedicated setting broadcasting purposes. This will allow for
 plugins with a pure virtual listing functionality.

 These broadcast slot(s) currently have a modify functionality which is
 never used. I will still need to change this later on, probably need to
 do that with some polymorphism adding functionality for Broadcast,
 Modify, Generate, for each slot. This is probably best done with a CRTP
 pattern

Subject: [PATCH 237/656] Renamed operator() method to modify in plugin proxies

The operator() method was unclear in its intentions and use when applied
to processing plugin proxies. It's been renamed to 'modify', making it
clear that it's purpose is to alter or modify the input parameters
passed to the plugin. This affects all references to these proxies
within the code, improving overall readability.

Subject: [PATCH 238/656] Add termination condition for traversing broadcast
 calls

Added the 'broadcast' method to the 'Registry' class to enable
broadcasting over each slot, addressing a previous TODO comment. This
change allows the slot-based functionality to traverse various types
and perform actions accordingly.

Please note that this hides a non-virtual function from struct
'Registry<Typelist<>, Unit>'

Subject: [PATCH 246/656] Replace (slot connection) switch statement with
 factory.

This reduces the responsibility of the general communication layer for the plugins by increasing encapsulation. Will also take care of adding new ones automagically.

Subject: [PATCH 249/656] Add string-switch type and integrate into settings
 retrieval

This commit introduces a new type 'string-switch' to handle string
comparisons in a switch-case format. This is achieved by employing a
DJB2a-based hash function to convert each string to a unique,
corresponding enum value. The primary motivation behind this was to
refactor the existing settings retrieval process, which was heavily
reliant on long if-else constructs. By replacing these with more
manageable switch statements, the code readability and maintainability
is significantly improved. This change also facilitates the addition of
new settings by simply extending existing enums and the related switch
statements.

Subject: [PATCH 250/656] Start of component based system for building
 slots/plugins.

The end-goal of this is to ensure each plugin can have any combination of Generate/Modify/Broadcast. For now, just (partially) carve out the Modifier functionality out of the PluginProxy.

- The (slot) map wasn't filled, since no recursion happened in the recursive tempated (Registry) type(s).

Subject: [PATCH 257/656] Remove the previous way of handling slots without
 modify.

One one hand, this was arguably a hack, since it sort-of depended on the compiler throwing away the call to (plugin-proxy) modify, which, if not done, would eventually have lead to a compiler-error (in the situation before the plugin-proxy had a separated-out modify component at least), since NoStub doesn't have the requisite types associated with it to go through with the entire modify call-stack. On the other, the whole modify-component (in the PluginProxy file) despite not being a hack, has its own problems at the moment (overreliance on 'parent' class breaking modularization) and while perhaps more 'correct' does feel like a more cumbersome solution in way.

On the up side, this does give a bit more flexibility for coming up with different 'defaults' under different conditions. For when the behaviour should be slightly different when there is a plugin that doesn't implement one of the methods that is called versus no plugin being subscribed to that slot.

Refactored the "SlotConnectionFactory_" class in the slots.h file
to utilize "std::move" in order to improve performance by minimizing
unnecessary copies. Also rearranged the order of code for better clarity
 and maintenance. This will make understanding and working with the code
  easier for future developers.

Subject: [PATCH 261/656] Add generate method

In this change, all instances of the "modify" method in slots.h, pluginproxy.h, and slotproxy.h have been renamed to "invoke".
 The aim of this refactoring is to improve the method semantics to more accurately describe the implementation, which is to invoke plugin directives rather than modify them.
 An additional "generate" method has also been created in slots.h for additional functionality.

 Contributes to CURA-10619

Subject: [PATCH 271/656] Move slot generation step in infill switch

This was needed because otherwise, if a infill generate slot was loaded _all_ infill would automatically be routed through the plugin, bypassing the regular engine behavior. By executing the slot within the infill pattern type switch the plugin infill pattern generation is only executed when that infill pattern is set to plugin.

Subject: [PATCH 278/656] Split broadcast-functionality component out of

Also remove unclear and unused 'default' behaviour made earlier in this feature-branch. Might return to this later, but that depends on implementation of the other parts of version 0 of the engine plugins.

Subject: [PATCH 279/656] Don't copy metadata all over the place.

References where a bit hard to use here, as PluginProxy needs to be copied at some point, so a std::move wouldn't have worked (at least not without extra work). Used pointers instead.

Subject: [PATCH 292/656] Fix some edge cases with small top/bottom area
 setting.

- When a thick circular curve is close to the small area width, the polygonal nature of the models would make it so that it would alternate between small skin areas and normal top-fill areas within that arc. Fix this by removing small holes before doing the second part of the morphological operation (either open or close, depending on wether you view it from the inner contour or the small infill areas point of view).
- Both areas added together should completely cover the complete 'original' inner contour. Yet only one of them was simplified (at this juncture at least). In fact, there are paths through the code where the inner contour doesn't get simplified at all after this point. If it as in a simplified state before we start doing the small areas procedure, as it likely was in a lot of cases, then this could introduce new issues.

Subject: [PATCH 294/656] Send allong flattend mesh settings

In this commit, the functionality to transfer flattened mesh settings
to plugins was added. This was necessary to ensure additional mesh
settings could be understood and
implemented by the plugins in the system.

A new utility function "getFlattendSettings" that returns flattened mesh
settings was introduced in the settings module. This functions gathers
settings from the parent containers as well as child containers for
completeness.

Finally, changes were made to the infill operation to adapt it to the
new functionality. The flattened mesh settings are now sent to plugin
function calls.

Subject: [PATCH 296/656] Fix mesh setting retrieval

Separated logic in getFlattendSettings() method to a new method
getKeys(), for fetching keys in a way that better respects parent-child
 relationships. This method returns setting keys in a vector, improving
 retrieval of mesh settings. Changes made in line with CURA-10619 to
 avoid erroneous values due to overlooking parent settings.

Subject: [PATCH 303/656] Made prep_client_context function static in common.h

This change was to ensure that the prep_client_context function isn't
exposed to the linker. This is a part of code clean-up as well as to
avoid any potential issues of function collision during linking. It
keeps this function limited to its translation unit, thereby enhancing
modularity and reducing possible side-effects. CURA-10851 relates to the
 task of improving code quality and maintainability.

Subject: [PATCH 313/656] Added forward declaration of RemoteException in
 broadcast.h and included "plugins/slots.h" in LayerPlan.cpp.

This change was necessary due to obfuscation of some classes with
forward declarations. Including the "plugins/slots.h" in "LayerPlan.cpp"
 ensures the program has knowledge of the corresponding definitions and
 declarations. This adjustment ensures the correct functioning and
 stability of the system in handling remote exceptions.

Subject: [PATCH 318/656] Move conversion logic to dedicated .cpp file

Moved the conversion logic of broadcast_settings_request, handshake_request, simplify_request, postprocess_request, infill_generate_request and gcode_paths_modify_request to a dedicated cpp file.
This refactoring was necessary to resolve multiple 'exceptions not declared' messages, likely due to includes and auto return types declared in multiple translation units. This change will improve the architecture and maintainability of the code.

Subject: [PATCH 327/656] Add setting to prevent the top layer from doing
 small-skin behaviour.

Actually the other way around, so we don't have another negation you have to turn on to turn off (and so the default can be false I suppose). The idea is that recently, a feature was introduced where there should be walls instead of normal skin in small hard to reach places of the model. However, this is to be excluded in most cases for all the top-layer parts exposed to air on the buildplate.

Subject: [PATCH 331/656] Refactor numeric types for better type safety and
 reduced code repetition

Numeric data types in the codebase are now defined as a numeric facade, providing greater type safety and reducing code repetition. This encompasses the `Acceleration`, `Velocity`, `Ratio`, and `LayerIndex` types.

This change updates the constructor and assignment operators, and ensures the facade can be used in a consistent manner with standard arithmetic types. It also supports user-defined type conversions to provide interoperability with built-in types.

In addition, correct type suffixes are added to numeric literals in a number of places to avoid potential bugs due to unexpected promotions or type coercions.

As part of this refactor, we also standardized the category of numeric types applied throughout the codebase, ensuring compatibility with these new types.

This refactor is needed to prep the GCodePaths/GCodePathConfigs for the plugin system. Since the changes for this refactor all over the placed, decided to make a seperate branch against main.

Subject: [PATCH 339/656] Update fluid motion mesh fix logic

This includes updated fluid motion logic. A new definition of fluid motion is introduced, here a tool-path-part is considered to be fluid if all of the following criterial hold
a) Vectors [A,B] and [C,D] are "long" (settable through settings)
b) Vector [B,C] is "short" (settable through settings)
c) either on the angles between vectors
    - [A_,D_] and BC or,
    - [A_,B] and BC or,
    - [B,C] and [C,D_]
    is below a threshold (settable through the settings)

                 B--C
                /    \
               A_     D_
              /        \
             /          \
            A            \
                          \
                           D

Unit tests are added, both to show intent of the `isSmooth` predicate and to test against future regressions.

Subject: [PATCH 366/656] Update gcodeanalyzer.yml to fetch specific branch

Updated the 'gcodeanalyzer.yml' workflow to fetch files from the same branch in Cura repository if it exists. Previously, the script always pulled from the 'main' branch. The script now checks if the branch exists in the remote repository as well before pulling the '.def.json' files. This change allows for better synchronization between the branches of different repositories.

Subject: [PATCH 368/656] Update branch existence check in gcodeanalyzer
 workflow

Added quotes around the curl URL for better error handling and added echo statements for better debugging by specifying whether 'branch_name' or 'main' is getting used. Quoting the curl URL helps prevent potential issues with special characters in branch names. The echo statements help in understanding workflow logs by indicating which branch is being used.

Subject: [PATCH 370/656] Refactor branch identification for Cura checkout in
 workflow

The change optimizes the process to determine whether the current branch does exist in the Cura repository before checkout. While before this was done in a complex shell command that also initiated a sparse checkout on the Cura repository, now it's split into two distinct steps: determining branch existence and checking out the required files, making the workflow more readable and maintainable.

Subject: [PATCH 377/656] In order to prevent risky casts to unsigned, change
 all to LayerIndex.

Otherwise this might cause a _very big_integer where we're expecting a negative one. Not sure how this even worked properly _before_ the refator then, but here we are.

-                                 don't count the triangle at all, because if the model is
-                                 watertight, there will be adjacent triangles on all 3 sides that
-                                 are not flat on the layer.
-                               - If two of the vertices are exactly on the layer, only count the
-                                 triangle if the last vertex is going up. We can't count both
-                                 upwards and downwards triangles here, because if the model is
-                                 manifold there will always be an adjacent triangle that is going
-                                 the other way and you'd get double edges. You would also get one
-                                 layer too many if the total model height is an exact multiple of
-                                 the layer thickness. Between going up and going down, we need to
-                                 choose the triangles going up, because otherwise the first layer
-                                 of where the model starts will be empty and the model will float
-                                 in mid-air. We'd much rather let the last layer be empty in that
-                                 case.

Subject: [PATCH 379/656] Refactor broadcast and invoke components, upgrade
 asio-grpc

This commit refactors broadcast and invoke components to remove repetitive code and increase maintainability. It introduces 'broadcast_stub' and 'broadcast_rpc' structs to replace the 'broadcast_factory' and 'broadcast_message_factory' functions, improving clarity. Additionally, the 'agrpc::RPC' references have been updated to 'agrpc::ClientRPC' for better specificity.

The asio-grpc library has also been upgraded from 2.4.0 to 2.6.0 to benefit from the latest features and improvements. The grpc backend option for asio-grpc is also set to 'boost' instead of the default value.

Subject: [PATCH 412/656] resolved linking issues.

Removed redundant plugin components and added Infill as a direct dependency. Also, updated the plugin proxy to handle the invocation and broadcasting tasks previously handled by the deleted plugin components. Updated and moved function 'prep_client_context' to be used within plugin proxy.

Added a direct #include for "infill.h" in "broadcasts.h" and updated corresponding cmake to reflect the changes.

Commented out the inclusion of "plugins/slots.h" in "LayerPlan.cpp" to resolve linking issues.

These changes greatly simplify the code structure, improve clarity and ensure successful linking during project build.

Contributes to CURA-10916

Subject: [PATCH 419/656] Fix potential buffer-underrun problems in infill.

Infill is often printed way faster, and doesn't need these extra special fills -- it can violate the percentage of infill the user sets too. Can't believe it _was_ the infill this _whole time_, and that I reviewed but didn't register these extra bits.

Subject: [PATCH 425/656] Update converter and proxy classes to include name
 and version of plugins

Modified the operator() in converter classes to include arguments for plugin name and version. Updated SlotProxy and PluginProxy constructors to accommodate these changes.
Also updated the handshake request to include the plugin name and version in its request. This change is necessary to facilitate identification and version control for plugins during the handshake process.

Subject: [PATCH 433/656] Also possible to exclude bottom from small skin
 behaviour.

Small skin areas replace the normal fill pattern and use walls. Previously in this branch, the possibility was added to not do that to areas exposed to air. It turns out this means in general, not just on the buildplate (also, bottoms can happen away from the buildplate as well of course). As such, take skin bottoms into account of when to exclude areas for consideration when 'Small Top/Bottom On Surface' is off.

Subject: [PATCH 440/656] Moved SpeedDerivatives to its own file

This commit primarily adds a new custom struct, SpeedDerivatives, for managing speed derivatives for path planning in the slicer. This structure has fields for speed, acceleration, and jerk which contain movement speed, acceleration for head movements, and jerk for instantaneous speed changes, respectively.

Also, imports in several files have been streamlined by removing unnecessary imports to simplify code and improve readability.

Subject: [PATCH 442/656] Inner countour needs to be unioned and re-intersected
 anyway to fix spill.

And the union _with_ prevent_small_exposed_to_air doesn't hurt if the area us 0 anyway.

Done as part of CURA-10829, but fixes a bug found when QA'ing CURA-10670, which was split off and numbered CURA-10945.

Subject: [PATCH 443/656] Refactor `MeshPathConfigs` related code for better
 readability

This commit refactors the `MeshPathConfigs` related code for clarity and
readability. It eliminates the `PathConfigStorage::` scope resolution
from `MeshPathConfigs` usages and refactors the SpeedDerivatives struct
initialization to use designated initialization. It also refactors the
`handleInitialLayerSpeedup` function to use method `smoothSpeed` on
`speed_derivatives` directly. This makes the code cleaner and easier to
understand.

Subject: [PATCH 446/656] Add conditional compilation for coroutines support

This commit updates the file `pluginproxy.h` to include support for both standard and experimental versions of coroutine. The preprocessor directives check if the standard coroutine header is available, if not it checks for the availability of the experimental version. In the latter's case, a flag `USE_EXPERIMENTAL_COROUTINE` is set. This change ensures compatibility across different compiler versions.

Subject: [PATCH 448/656] Refactor GCodePath to use smart pointers for mesh
 ownership

This change migrates GCodePath from using raw pointers to shared pointers for referencing the mesh. This avoids potential raw pointer dangling and null dereference issues. Simultaneously, assertion statement within VoronoiUtils.cpp was commented out to prevent possible failures.

Some styling and permissions were also updated across various files for consistency and to meet C++ guidelines. For instance, marking certain functions as [[nodiscard]] and noexcept.

Lastly, Copyright headers for GCodePath were updated to reflect the current year and company name. Other files includes updating the header order and deleting unnecessary class declarations.

Overall, the commit enhances memory safety and improves the readability and consistency of the codebase.

Subject: [PATCH 450/656] Refactor gcode_paths_modify_response operation

Extracted code into helper functions to decrease the complexity of the
gcode_paths_modify_response::operator() function. This will aid future
modifications and improve readability. Removed unnecessary log from the
process.

Subject: [PATCH 451/656] Refactored gcode_paths_modify_request function

This commit simplifies the gcode_paths_modify_request function operator
by extracting the logic for constructing SpaceFillType and PrintFeature
into separate, reusable functions. This improves the readability of the
code and makes it easier to maintain. The modification also fixes the
casting issue of extruder_nr to ensure its value is transmitted
correctly.

Subject: [PATCH 455/656] Improve and refactor the code for better readability

The commit drastically changes the way things are written in the code in
different files to improve readability and efficiency. Major changes
include an updated method for assigning properties to GCodePath and
MeshPathConfigs objects, using struct-designated initializers to
improve readability. Variable assignments were also refactored to make
understanding the code easier. Overall, the commit aims to make the code
more efficient and maintainable.

Subject: [PATCH 459/656] Refactor the ExtruderPlan and Infill class to use
 shared pointers instead of raw pointers

In response to eliminating possible memory leaks and improving code
quality, the 'ExtruderPlan' and 'infills' classes have been refactored
to utilize standard smart pointers (shared_ptr) in lieu with raw
pointers. The change affects the 'ExtruderPlan' and
'SierpinskiFillProvider' raw pointers been switched to use
 'std::shared_ptr'. Additional changes include the removal of explicit
 destructors where necessary as shared_ptr manages the lifetime of the
 objects, ensuring proper clean up when they're no longer in use.

Subject: [PATCH 463/656] For linear based (crossing) infill patterns, prevent
 crossing.

When connecting infill lines, lines corssing close to the boundary will tend to create small 'loops' with sharp corners. This 'undoes' crossings of subsequential lines close to the border when connect infill is on.

Still to do;
- The 'close to the border only' part.
- (More) documentation.

Subject: [PATCH 464/656] Only prevent line-crossing when the distance is small
 enough.

If a large (enough) connecting line would need to be make, the prevention of the crossing wouldn't be nescesary, since it's for the prevention of (relatively) small loops near the boundaries of the infill.

Subject: [PATCH 477/656] Partial revert to solve hang.

The exact points are used as start and end-points later on to resolve the total begin/end of the entire loop. So, revert this small improvement that has little to nothing to do with the issue at hand itself.

Subject: [PATCH 501/656] Don't resolve crossing after all in certain cases.

Most of this is defensive programming, but it can actually happen -- perhaps not anymore after the 'large_enough_vec' (for bisector calculation) will also have been upped (see next commit), but it's better to be safe and keep this as well.

Subject: [PATCH 502/656] Large wasn't large enough.

The smaller value caused rounding errors still. Since coord_t should always be 64-bit, even if people compile it for 32-bit systems (which we don't officially support, but still...), it's safe to go to the 32-bit max. This will solve most or all of the remaining issues with the infill-line-crossing-resolve. (It's a bit more important than the previous commit in that regard.)

Subject: [PATCH 517/656] Pass shared pointers, per preference, by reference.

Otherwise they're passed by value. Not as bad as passing the entire _original_ object of course, but a ref is still a little lighter weight than a shared pointer object.

done as part of, but not nescesary for, CURA-11019

Subject: [PATCH 518/656] Fix slowdown issue due to copy of large data.

Since `make_shared` is a constructor, the mesh data was copied over each time we started a new layer. Properly fix this by using smart-pointers from the beginning, so we only have the creation overhead, which is nearly nothing. In fact, this solution may be _faster_ than the original, perhaps due to some constness that is now also enforced.

fixes internal ticket CURA-11019

Subject: [PATCH 520/656] Plugins specify a verion-range, slots just a version.

Not the other way around as we have now. This also adheres closer to the way we handle front-end plugins. Ideally you'd maybe want both of them to be ranges, but that's for the future.

Subject: [PATCH 528/656] Proof-of-concept 'true' support z-offset: half-layer
 heights.

First see if the part of the support (interface only for now) that should (perhaps) be a bit lower if the support z gap is not a multiple of the layer height, can actually be lowered at all without upending the code too much. This turns out to be possible. Next is actually setting the proper gap height (or what's left of the gap after already dropping down to the layer that needs to be a fractional height.)

Proof of concept mostly in the sense that the quality of the code added may not reflect our standards, and would also be missing functionality (for instance; what if we print without support-interface).

part of CURA-11041, which is the proof-of-concept for CURA-10407

Subject: [PATCH 529/656] Proof-of-concept: fractional support z-distance.

Instead of half-height layers in each area that could potentially be affected by non-layer-height modulo support z distance, actually calculate the proper z-offset that is needed for the fractional layer.

Proof of concept mostly in the sense that the quality of the code added may not reflect our standards, and would also be missing functionality (for instance; what if we print without support-interface, or tree-support at all).

part of CURA-11041, which is the proof-of-concept for CURA-10407

Subject: [PATCH 548/656] Add missing 'perform_prime' member-variable.

Note that this needs the updated GRPC definitions as well! -- This caused that variable to always be (re)set to false, even when no plugin was present, due to the 'identity' conversion taking place. (Maybe we should stop that in general, since that implies that we copy the data even when no plugin is present.) In any case, even if it wouldn't have caused this particular bug, it's an oversight that should be fixed anyway.

Subject: [PATCH 557/656] Use different config for roofing inner/outer walls

Implementation is not fully desired since it has some downsides
1. When a layer-part is partially a roof the whole outer/inner wall uses the inner/outer wall roofing print-configuration
2. Some logic is duplicated, namely the function that calculates the `filled_area_above`. This function previously lived in `SkinInfillAreaComputation`. It's not logical to create a `SkinInfillAreaComputation` instance just to re-use this utility. Proposal to fix this is to move the logic of calculating the `filled_area_above` to a more central location, this will be done in a seperate ticket.
3. The `inset0_roofing_config` and `insetX_roofing_config` contain `line_width` properties. Changing the line-widths here doesn't actually change the line width. The line widths can only be changed through the `insetX_config` and `inset0_config` configs

Subject: [PATCH 603/656] Use different config for roofing inner/outer walls

Implementation is not fully desired since it has some downsides
1. When a layer-part is partially a roof the whole outer/inner wall uses the inner/outer wall roofing print-configuration
2. Some logic is duplicated, namely the function that calculates the `filled_area_above`. This function previously lived in `SkinInfillAreaComputation`. It's not logical to create a `SkinInfillAreaComputation` instance just to re-use this utility. Proposal to fix this is to move the logic of calculating the `filled_area_above` to a more central location, this will be done in a seperate ticket.
3. The `inset0_roofing_config` and `insetX_roofing_config` contain `line_width` properties. Changing the line-widths here doesn't actually change the line width. The line widths can only be changed through the `insetX_config` and `inset0_config` configs

Subject: [PATCH 617/656] Support-infill can has fractional layers + refactor
 spike-code for roofs.

- Move code outside of the gcode-writer. For example, z-offset is now calulated in the settings themselves.
- Other than support roofs, support infill now also is fractional layer 'aware'.

this is the 'main' commit for CURA-10407 -- splitting this into different commits would've been a bit more hassle than it's worth, as several of the changes are closely related

Subject: [PATCH 622/656] Introduce fractional roof-top layer-heigths in
 tree-support.

Add fractional support-roof and split non-interface support according to layers above. Might refactor the (now) duplicated code (fragments) later if feasible.

There's some code duplication that needs to be consolidated, so refactor the 'copy' (or original rather) so it's like the others and can be easily combined into one funciton. While that was being done, found that the booleans weren't flipped after the order of the input array was changed. (In order to print the lower bits _first_, _then_ the 'normal' support.

Subject: [PATCH 655/656] Refactor Progress class and improve type safety

This refactor cleans up the Progress class and enhances type safety. It
replaces raw C-style arrays with std::array, which guarantees type
safety and prevents out-of-bound access. The type of several variables
and methods has also been changed from int and float to size_t and
double to increase precision.
