Hi -

I have been trying to draw a simple bitmap using gl calls
from a pfChanDrawFunc callback... Everything works ok
except that the image I draw is always "on top" of the
performer image. I have called lsetdepth, ortho, and zbuffer
but to no avail. When I move the far plane in my bitmap image
does disappear at the correct value. When I look at an object
in front of my bitmap it ALWAYS appears to be behind it even
though it disappears when I move my near plane out and my
bitmap remains...

Any suggestions would be greatly appreciated!
