With Joe's assistance on some magic styling for the
frames, I was able to get the single frame that I use
as the notebook pane container to adopt the gradient.
Attached is a pic showing this.

This is fine in general - but I have issues where the
guys here complained because on another pane we make
use of a panedwindow.  That uses the standard bg, which
is subtle but visible against the gradient bg.

I wonder what effect named colors will have on this as
well?

I did send that patch that I tried before regarding the
use of DTPB().  It didn't really work, or rather have
visible effect (it compiled and ran just fine) ... :(
