But only in 256 colors, not rgb.  It is rgb painting that I am totally stuck
on.  I was coding a slow xbm display routine in pure ruby (pretty easy)
until I dicovered this limitation.  I could do slow xpm with 256 colors
easily, but now I'm working on adding fltk classes to ruby-fltk instead.

To answer your question, my first priority is getting arbitrary rgb values
up on the screen.  My second priority is getting all fltk image support
going.

Right now I am stuck getting ruby.h to work in VisualC (I know that is a
stupid thing to be stuck on, but I'm not a VisualC expert).  I was able to
compile fltk itself in VisualC.

Do you know which of these would be most important to you?
Or could you live with whichever is easiest to add?

Generally adding Ruby-FLTK support for additional FLTK
classes is pretty easy. The exception is when the
underlying FLTK objects have unusual memory management
issues. One or more of these may fall into that category (I
haven't checked yet).

Drawable::point allows you to draw single dots at a time.
Obviously this would be slow if you are doing much drawing,
but it might be a temporary workaround.
