Philip Gruebele 7eb1ac5143 dwrite: Pass correct font key when adding glyph to cache. 
Without this fix, the font cache was filling up with lots of duplicate entries,
and getting cache misses, thereby causing font-intensive applications
to be very slow (e.g. AvalonEdit).
This fix provides 30x speed increase when processing glyphs.
