Yes, but Paul wants something that also contains an additional transparency
component on each pixel (he needs ARGB, not RGB). To my knowledge, no common
font format supports that very well, so I'm certain that he'll need to write
a custom font driver for it.

Note that this is necessarily a difficult thing. I've implemented several
custom bitmap font driver in about 500-1000 bytes each (since the file
storage scheme was really simple).
