If the font face doesn't include a Bold or Italic version, we still want
to display the font as bold/italic, so we fake it with freetype.
This also prevents recurring error messages where the outline font warns
about "substitutes" within the same font family.
Also allows variants on the weight descriptor to be used without
throwing a substitution warning

Also fixes a bug that we'd render too many glyphs when some glyphs
were combined. (To test, render "text" in Apple Chancery. The opening
"te" is combined into a ligature after which we render an extra 't' at
the end.

Also fixes some plot bugs with arcs.
Also moves polygonization of arcs (when required) in plotting code
from 5 degrees to calculated based on ARC_HIGH_DEF.

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
