Are the palettes all static, defined by the driver? If so, then driver
itself can map a passed palette index to RGB.
Even if someday drivers allow modification of the hardware palette, the
driver can still map RGB to index itself.
The only value I see to the palette index flag is to have 8 or 16 "standard"
colors that programs can count on, but even that is kind of superfluous -
they can just specify a "standard" RGB (black, white, yellow, green, etc.
like Netscapes color names) and let the driver do its best.
As for the differences in mapping between RGB bit layouts, again, the driver
can do the mapping, no?

Brad
