[PD] Masking Geos in gem help

I figured it out I think. The problem was that the example used in the gem examples was clearing the
color buffer and the depth buffer so no other object could exist. What I did was define the colormask
to 0
for stencil and 1 for not stencil that way the color and depth buffer did not have to be cleared. I know
nothing of opengl but I read this at an opengl gaming website and it worked. I have attached the
example.
Thanks,
Alain
fixed.
