Hi, a program I am developing which uses the sphere library runs just
fine on an IRIS 4D/220 VGS, but when I run it on a nearby Indigo XS24,
the SPH_HEMI seems to get set true by default with SPH_ORIENT set to
FALSE (It draws hemispheres which show up as you rotate objects on
the screen).  If I set SPH_HEMI and SPH_ORIENT to TRUE, this problem
goes away, but then z-buffering goes away too and the appearance of
spheres on the screen is as if they all have the same z-coordinate
and appear in the order in which they are drawn...  The Indigo is
running 4.0.5 and zbuffer is most definitely set to TRUE...

Oh, one more thing, this is in a GLX widget that this is happening...
