Text glyph caches and bug fixes. 

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
