How do I detect when the UserControl's Parent's BackColor Changes?  I Have a
user-drawn control that has a transparent background.  When the background
is transparent, I paint the parents backcolor behind an icon.  But when you
are in design time and you change the parent's backcolor, the backcolor of
the square of the usercontrol doesn't change.  I thought it would fire the
UserControl's AmbientChanged event, but it doesn't.  Any ideas?

To see exactly what I'm talking about, try it with my control:
