Plain text scrap

[adamwulf]

Add a feature where the user can type into pages on Loose Leaf. Something that should integrate and work with scraps in a clean way

• Float like scraps.
• Handle in bottom right to resize the square boundary.
• Auto bend text around other scraps on page.
• Maybe only bend around scraps above them? Or only below them?
• Also bend around all ink on base page. Do this by resizing to 1/40th of original resolution, making a 20 radius circle at every point that is non white, unioning all of them, and using that as the base page path.

Then user can add text scraps, type into them, move them around on a page, even resize them to fill the page

Also, add option to hide border when exporting scraps.
