Here is my situation: I would really like to be able to have more
communication with the display hardware than I currently have. What I
would like to do is modify a hardware colormap directly. In essence,
changing the way pixels are displayed, without actually scanning and
changing the pixel data values; just change the display colormap.
Maybe I CAN do this, but I just haven't figured out how yet. And I
also know that this is getting away from the hardware independence
Java enables us to use, so even a way for certain platforms would be
nice. (Maybe build a library for certain platforms that gives lower
level access to display hardware.) This would be great if I want the
"look" to change, but not take the time (in software) to actually
recompute the data.

Any advice/help would be appreciated. Thanks in advance!
