Whoa there, 

I am not sure having the Panel export pixmaps/do special panelly
weirdness for its background is a good idea...  In previous discussions
with Panel2 folks I emphasized that the Panel needed to be
theme-compliant...  If so then the Panel applets should get their
background info (including pixmaps) from the theme!  Alex, if
theme-compliance is one of the ways you have in mind that Panel should
be more like normal GTK+ widgets, then that's great.

I think that having the Panel do significantly non-GTK+-ish things for
its rendering is a bad idea.   It's certainly a nightmare for
accessibility.  And surely if I change my desktop GTK+ theme via gtkrc,
I would want to panel to play along...
