Is this net.graphics or net.boring? All, or at least most, of the other
groups have ongoing discussions. This seems to be a variant of net.wanted:
"we just got device such-and-so, does anybody know how to use it?".
I can't believe that either 1) no-one is doing any graphics work, or 
2) everyone knows exactly what they are doing. So how about some discussion
going on here? Let's talk about such things as:
   * what equipment you are USING, and to do what
   * what kind of graphics systems are out there
   * what are you doing research on
   * what problems are you having
   * what nifty solutions have you come up with for certain problems
   * anything else you feel is appropriate
Come on people, we can be as verbose as the AIrheads can't we?

To start the ball rolling here is a semi-reposting.
I have been generating color (that's colour for you people in Canada) images
using an 8 bit color lookup table. However, I have been unable to find any
good algorithms (or even bad ones, although I have invented several TERRIBLE
ones) to allocate my precious 256 entries in the color table. Of course it
would be a lot easier to generate the picture completely in 24 bits but then
what is the point in using a scanline algorithm for rendering? So, does anyone
have a way to allocate color table entries while a program is running with no
'a priori' knowledge of what the picture looks like?
