It should work, However the problem with this approach is that you'll
have bitmap fonts, which have the following drawbacks:
1. they do not scale nicely, so they would probably look bad in a printout
2. the bitmaps will increase the filesize considerably.

OTOH, using the gl2ps text routines which use the ps fonts have the
drawback that they do not support anything but "normal" text (i.e. no
LaTeX)
