After compiling, The font_include.o is about 110-120MB. When making Links, it cost more than 80% of system memory.

I tried using DFB DrawGlyph() instead of draw_bitmap() in print_letter(), and the performance is really very very poor... I think the reason may be that I create the font and then release it for every character; I'll try to reduce the times of font create()... > Are these fonts under a licence compatible with GPL?
