[GEM-dev] cvs-check ins

[zmoelnig at iem.at]

hi

in case anybody has noticed and wondered:

i have checked in some cahnges to the Geos section, mainly bloating the code.
all glu-objects (cone, sphere, cylinder, disk) have been re-written explicitly
(GLU is not used anymore), so the rectangle-texturing now works with them.
additionally i have done the same to [teapot], so the optional dependency on
glut is now removed and the teatpot still available (with rectangle texturing)

furthermore i have fixed the texture-code for all other geos that were still
missing. (except for the [curve])

mfg.as.dr
