A) Pure software drivers (VESA/VGA/NUL) support only double-buffered modes.

from `Mesa/src/glut/dos/Makefile.DJ' before (re)making GLUT. Beware, this
means you will never EVER be able to safely use `glut.dxe'!
Q) What is NUL driver good for, if I don't get any output at all?
A) For debugging. The NUL driver is very much like OSMesa. Everything is
done just the same as VESA/VGA drivers, only it doesn't touches your
video hardware. You can query the actual buffer by issuing:
DMesaGetIntegerv(DMESA_GET_BUFFER_ADDR, &buffer);
and dump it to a file.
Q) How do I query for a list of available video modes to choose as a visual?
A) This is an ugly hack, for which I'm sure I'll burn in hell.
First, query for a list of modes:
