Ok. I was getting very sloppy and left the RPM versions installed, and
then installed the tarball distribution assuming it would overwrite the
RPM.  Anyway, I cleaned all signs of xforms and lyx from my system and
compiled from scratch (bxform-088-glibc2.1.tgz and lyx-1.0.3.tar.gz) and
it worked fine at 8, 16, and 32bpp.

I modified figinset.C (diff is below, more elegant than before) and
recompiled. This also ran properly, and correctly rendered color EPS
figures at all resolutions tested: 8, 16, 32bpp

Unless anybody has had any problems, I suppose this patch is good.
