Setting complex instructions program and multiple delta instructions may
take a lot of time. An alternative is to create bitmap versions of the glyphs
for most important sizes so TrueType rasterizer will use them instead of
rendering outline glyphs and instructions program.
Bitmaps can be defined for any combinations of glyphs and PPMs. A font
may have only one bitmap for one glyph and one PPM or lots of bitmaps
for different glyphs at different PPMs - there are no limits.
FontLab supports import, export and editing of so-called embedded
bitmaps.
