I have a question about color index management. In all the books I've read about
GL, there is NO definition of how RGB colors must be distributed across color indexes;
apparently, it's implementation-dependent. However, if we look at the Palm, we'll see
it
has a "white" screen (by now, it's green, but the soon-to-come Color Palm will have it
white), and the pixels written to the screen are black, in contraposition with most PC
video
screens. GL's reference manual says that the default clear color (the one specified
with
glClearColor() ) for RGB windows is (0,0,0), and for color index windows, it must be
0. So
this ends up in we have a default clear color of "black" for RGB windows, but a
"white"
(color 0) color for color index windows in the Palm! I perfectly understand one thing
is the
standard, and another thing (sometimes very different) is what people actually do. So,
my
question: Should I use the color indexes that the Palm uses now (0 = white, max =
black), or
should I remap these indexes to obtain a closer match to the current implementations
of GL,
including Mesa?
