Hi!

We were wondering here if there is a way to set the Z-Buffer to 30bits
on our iR using OpenGL and Motif. Running findvis does not report any
such combination while xdpyinfo reports the existance of such a visual.
No matter what I do to request the combination I want I get a 24(23) bit
depth buffer. What am I doing wrong - or not?

I would like something like

PFFB_RGBA
PFFB_DOUBLEBUFFER
PFFB_DEPTH_SIZE, 30
PFFB_RED_SIZE, 10
PFFB_SAMPLES, 4
PFFB_STENCIL_SIZE, 1

Any suggestions appreciated!

Scott
