Hmmm...can we get away without platform specific panel manager?  This
implementation watches the bottom area of the screen to raise/lower all title
bars for minimized panels. If I understand correctly, it will do this even if
the mouse is at the bottom of an open panel.  Seems better to handle this within
each individual panel so that if the panel is minimized and the mouse hovers
over the bottom area of the screen where that panel is located (might not be on
minimized panel directly), then raise all titlebars of minimized panels.
Otherwise, if the mouse is in the lower portion of an open panel, leave
minimized panels alone.

Done.
