Rewrite QDFBScreen::exposeRegion

This code should be a noop in the case where one has a proper dfb cursor
and proper dfb window handling. This was the only case it actually
worked.

This patch makes it work for a screen cursor rendered by Qt and sets
exposeRegion up to work for using an offscreen backing store.

Since one can't query the background color set by directfb this patch
also adds a connect option to set the background color. This is needed
for erasing the background when the mouse cursor moves.
