Specific alternatives are:
1) Repeatedly call FT_Outline_Render using FT_RASTER_FLAG_DIRECT onto
a target bitmap.
2) merge outlines and call FT_Outline_Render once, which does not have
to be direct but needs preset bitmap.
3) merge outlines, call FT_New_Glyph and wrap them, call
FT_Glyph_Render to render
I have to say that FreeType does come too close to being a graphics
library. Let's make the interface decision in that direction very
judiciously.
