We've looked into the "Standard" colormap stuff, but there were some problems with the earlier versions of the proposal. We'll look at the ICCCM to see what's specified in the latest rev. -- Charles

One solution would be for the server to make available a portion of the
colormap (say, some percent of the unused bins, good neighbor policy
requiring that no-one have the whole map). There exist algorithms
for mapping from one arbitrary set of colors to another, smaller set,
including some authored by yours truly (e-mail me if yer interested).
The client process would either permit the server to do the transform
on the image, or would be informed that it must do so -- If good results
are achieved by mapping from a real-world image of 1M colors to 256 colors,
It seems plausible that mapping from 256 to say, 16, could give quite good
results. Probably not true for a CAD Line drawing, but then we get into
how server and client negotiate how much of the colormap the server is willing
to give the client, and at what "cost".
