Log message:
Changed the concept of how we solve the problem that we need to
clear the window background to its background color. X does this
automatically before sending expose events but DirectFB doesn't
know such a thing as an expose event.
We used to do this similar to what the LinuxFB backend does by
using our own implementation of gdk_window_invalidate_region that
also clears the invalidated region. The problem is that our
implementation is only called from inside the DirectFB backend
and thus we missed a few situations where we needed to clear.
I have tagged this state BEFORE_INVALIDATE_CLEAR_REMOVAL.
The new concept is to clear the background in begin_paint_region().
Since GTK+ surrounds all exposes with calls to begin_paint_region
and end_paint_region this works pretty good and solves almost all
the redraw problems we've had. It also makes our backend cleaner
and smaller.
