[Devel] Embolden/Obliquing with cache

[Ken Hancock]

I'm trying to implement embolding and obliquing using the new cache 
routines.  During my rendering routine, I normally call 
FTC_SBitCache_Lookup and then render the bitmap into my destination bitmap.

For obliquing and embolding, I don't really require the cache -- it's 
done infrequently enough that using the cache for such a purpose would 
probably slow the system down by effectively reducing the cache size.

Obliquing can be done with a simple FT_Glyph_Transform and 
FT_Glyph_To_Bitmap.

Embolding is a bit more complex.  FT_GlyphSlot_Embolden takes a 
FT_GlyphSlot while FTC_ImageCache_Lookup returns a FT_Glyph.  Can I take 
advantage of the glyph cache and then somehow coerce an FT_Glyph into an 
FT_GlphySlot?  Do I need to spin my own embolden?

Thanks in advance,

Ken
