Hi Dave,

Making the background transparent (for wxPanel) proved to be very hard in
wxWidgets. After a lot of googling and testing I managed to imitate the
background gradient. I do this only for wxWIN. It should work without this
hack on wxGTK and wxMAC.

Done. (I hope I did it right)

Please find the changes in a new patch to review. Please also run embed-xrc
again.

I have also modified the .mk files. But at this moment I have no way of
testing on wxGTK and wxMAC.
