I attach another small changeset which implements indexed images. Like
many other changes I submitted, this actually consisted of much
planning, followed by a lot of browsing through code to see how to do
it, and then finding out that Michael Goffioul already though of it
and I just have to use his functions :)
In this case, adding indexed image suppoert consisting of changing
just one line (actually just one word: cdata -> color_data)

Together with my previous changeset to colorbar, the colorbar demos
now work under fltk on-screen.
