solvespace/textwin.cpp
Jonathan Westhues 273339d5c4 Add TrueType font support to SolveSpace. This uses a modified
version of the code from SketchFlat, with all arbitrary limits
removed.

The TTF text is its own entity, and that entity includes the
font file basename and the text. That's an extra 128 bytes in the
entity, which is around a 50% increase, kind of a shame. It was
simple, though.
