Well, there is a problem here.  ToString() is officially documented in
the Object base class as being just a debugging tool, and not intended
to be used for real use.  A few classes though, use ToString() as their
officially supported method of stringifying themselves (like
StringBuilder.ToString).

So in the above scenario, ToString() looks like debugging, but in the
Gtk# case, we could make it a bit more useful.  For instance, the rgb:
notation from X11 can be copy/pasted in source code or program command
lines, or input fields to specify a color.

I do not feel strongly about this though.

Miguel
