That really doesn't buy you much when you go to draw the reliefs of
borders does it?  Still you need to define how to draw them or you
need an entire pixmap to do it.  If you require a pixmap, memory
is sucked away.

We could perhaps be able to define "relief" as a separate pixmap that
is small and use the border stuff and have the center be one pixel...
that wouldn't take up much memory I suppose.

Even so, if you had a theme which was more complete than others, you
could have themes pile up on top of each other - for example, I have
my 57chevy theme and I didn't define a filesel widget.  So in my 57chevy
theme I put to fallback to themes mac,win95,motif if available.  This
makes things more complex and perhaps isn't even desirable.

The fallback is more important in widget sets than say, in E, because
if a new widget pops up and our theme doesn't handle it, it would be
nice to choose themes as backups which closely match.
