I made the widgets for my application.  But, some of the widgets
may be useful outside of the application (for example, a knob widget).

About 4 or 5.

The colors dont have to be exact, but yah, the application shouldn't
be broken.  I dont think this is a problem though, is it?  Given
that I have only a handful of colors and they are well seperated
from each other.

This isn't strictly necessary, but it would be nice if the application
let the user change the colors.

well, I don't think gtk_paint_* had all the primitives I needed.
I suppose I could make the widgets use the default colors, but only
if I have a decent way to control what those colors are in my
particular application.  It seems like I should be able to do this
with a gtk style file, but I haven't figured out the details of that
yet.  But that would require that a style file be installed when
the user runs the program, unless there is some way to compile in
a default style?
