dacBits =
ScreenDacBits(windowPtrOrScreenNumber)
What is the precision of the DACs on this graphics card?
At present you need to know the bit depth of your graphics board's DAC
to determine how to write its CLUT, i.e.
Screen '
SetClut' or 'Gamma'.
Use this routine and
ScreenUsesHighGammaBits, instead of the the brand-
and platform-specific
IsRadiusThunder10 and
IsATIRadeon10, to keep your
program as general as possible, not tied to particular hardware or
platform.
The value is set in
PrepareScreen.m.
