stereo visual support for ATI Fire GL4
Stereo is not supported in the initial release of the FireGL X1/Z1 driver. It will be supported in a
future release.

visual support for other graphics devices

The OpenGL product can also be used with the Virtual Memory Driver (VMD) in Virtual GLX
mode (VGL). VMD allows you to use many X11 drawables (local or remote) as "virtual devices"
for three-dimensional graphics with OpenGL. This includes rendering to X terminals and other
non-GLX extended X Servers.

*Double buffering is set to True (1) if the X visual supports the X double-buffering extension (DBE).
**Alpha will only work correctly on 12- and 24-bit TrueColor and DirectColor visuals when the X Server does not use the
high-order nybble/byte in the X visual. Also, note that when alpha is present, Buffer Size will be 16 for the 12-bit visuals
and 32 for the 24-bit visuals.
