- It turns out that the geometry collection of the geometry of a glyph run may not be of the same length as the glyph run string since spaces (etc) aren't represented. Ugh. For now I'll assume that glyphs not in my main glyph list (such as spaces) aren't in the geometry. Seems to be working so far.
- Coords of glyph geometries not quite lining up properly yet...
- I think I found the cause, bed time now.
