Allow scaling, rotating, and translating along X/Y/Z and per model.

Scale X/Y/Z:
  --sx <double>
  --sy <double>
  --sz <double>

Or scale X,Y,Z:
  --sc <double>

Rotate X/Y/Z:
  --rx <double>
  --ry <double>
  --rz <double>

Translate X/Y/Z:
  --tx <double>
  --ty <double>
  --tz <double>

NOTE: The specified arguments must be provided for all models! As in,
if you want to specify --tx for the last model, you must specify --tx
for the preceding models. Make it 0 for those models that do not need
translation along X axis.

For example:

   Slic3r --merge --dont-arrange --tx 0 foo.stl --tx 20  bar.stl

For example:

  Slic3r --merge --load default.ini -lm foo.ini foo.stl --lm bar.ini bar.stl

… objects

When printing models in a wellplate, the bed has to be lowered before traveling to the starting position of the next object.

…l-height

Add cmdline option to pass travel height while traveling between objects

* Do not undefine __STRICT_ANSI__

The `__STRICT_ANSI__` macro is defined by the compiler and it's undefined to undefine or redefine it.

Using `-U__STRICT_ANSI__ -std=c++11` is just silly. If you don't want strict mode, don't ask for strict mode. Certainly don't ask for strict mode and then undefined the macro that is defined by strict mode.

The correct solution is `-std=gnu++11` which doesn't define the macro in the first place.

* Stop defining _GLIBCXX_USE_C99 (slic3r#4981)

This is an internal macro defined by libstdc++ to record the result of
configure checks done when GCC was built.  Defining (or undefining or
redefining) the macro yourself results in undefined behaviour.

If the system's C library doesn't expose support for C99 or 'long long'
then telling libstdc++ that it does isn't going to work. It will just
mean libstdc++ tries to use features that don't actually exist in the C
library.

In any case, systems that don't support C99 are probably not relevant to
anybody nowadays.

* Don't look for wxWidgets if not building the GUI components.

* Remove OSX from travis build list because it is broken.

* Only look for nowide locally if the boost version is > 1070

* Use VERSION_GREATER_EQUAL instead for version check.

* add --rotate-x and --rotate-y to slic3r.pl command line parsing
and their correspondent implementation and documentation
I previously created issue slic3r#4862 to submit this change

* Allow for compiling with debug output turned on by default.
Automatically log at the DEBUG level if this is done.
Fix compile issue where Log.hpp wasn't available.

* Throw a runtime error if the number of solid layers grows above the total possible layers.
Edit the loop syntax to need the current shell thickness to be less than the minimum to add more layers (avoid infinite loop).

Add test to cover normal operation and regression for this layer arrangement.

Fixes slic3r#5019

* Don't add any facets to the read-in list if it calls out a vertex that is more than we have read in.

(assumes that we have the vertex list before the volumes, which should be guaranteed in a normal file).
Fixes slic3r#5061

* undo whitespace-only change.

* Refactor the test case to definitely cause a segmentation fault.

* Rename to .amf from .xml

* Quick port amf (slic3r#5068)

* Ports the basic deflate and related items from prusa3d/PrusaSlicer for AMF deflate.

Implements slic3r#4511

* Actually add the tests to read files.

* Push all  the utils into one header.

* Revise slightly to ensure we end up in the logic and just rely on strcmp to check the buffer against the magic key.

* Use more compatible CMake construction?

* Build using cmake3 on travis.

* Fix use of strcmp; remove unused config definition

* throw an exception if bad zip file

* Use correct string header for cstrings; terminate buffer.

* Insist on CMake >= 3.9, actually install it on Travis

* Use VERSION_STRING instead for boost

* Use VERSION_GREATER_EQUAL to look for 1.74 or higher when attempting to include nowide

* invert logic to do what we want

* All build systems are terrible in their own way.

* Fix duplicate symbols caused by double invocation of miniz.h

* Bugfix: sending G-code failed because of line number errors. slic3r#4847

* New --print command line option to send G-code

* Change links to slic3r.org from http to https
