Add direct handling of quadratic beziers to save compute time and number
of points. Update cubic interpolation to reduce number of points
generated for a given smoothness
Cache data on open and used cached data to avoid multiple re-calcs
Remove minimum line length and number of segments and replace with
standard max error level. Allows us to specify the tolerance of bezier
interpolation
1) Unify metrics between stroke and outline fonts
2) Unify handling of rotation and mirroring
3) Bug fixes in collision handling
4) Use of VECTOR2I (instead of VECTOR2D) for world-coordinates
5) Generate outline font overbar with rounded ends and fix rotation
bugs
6) Generate wxEVT_CHOICE events from FONT_CHOICE::SetFontSelection
7) Change text-item PNS SOLIDs to use compound shapes
