Indeed.  I've tried it, and it works great.  (Rounded button gadgets look
REALLY nice when done this way.) Unfortunately, I've seen very few programs
that use it.  Pity, since it makes things look very nice, and it's not very
hard at all.

In the 1.2 Enhancer manual, a description of this feature is on page 60,
and a partial example is on page 76.  This is the only place I can find
that describes it very well.

Good luck!
