It seems Keith is misunderstood. The term "sbit" as used in FreeType
really means "embedded bitmaps" (it comes from the TrueType spec).

It is only very remotely related to scaled bitmaps. And for now,
FreeType doesn't support them. However, this wouldn't be a very
difficult addition provided that you could provide some sources to
base this work upon.

I believe that Brian Stell has developed some bitmap scaling code
for Mozilla. It'd be nice if he could point me to the relevant
source files, I'd be happy to take a look at it..
