True Type font glyphs have error on some characters

This seems to be a parsing bug in IGlyphReaderExtensions. The 'O' in particular looks like it has an error figuring out if it is in a curve or not and renders the LineTo that seems out of place.

@prepare, any insight or suggestions you might have in how to fix this would be incredibly appreciated.
