FreeType doesn't contain code to scale and rotate bitmaps.  While
FontForge, for example, can create gray level bitmap fonts (either as
a BDF or as a TrueType bitmap font), I'm quite sure that most
platforms don't support the operations you want for those font
formats.

With other words, you either have to convert your font to pseudo
outlines (thus you no longer will have control over the gray levels),
or you have to write your own code to scale and rotate such bitmap
fonts.
