Don't reenter gdk_window_process_updates_internal

Its not correct for recurse gdk_window_process_updates_internal, as
the outer instance will overdraw the inner. So, protect against
gdk_window_process_updates() being called while in an expose
handler.

This shouldn't be a repaint problem, as eventually the idle handler
will cause the updates to be processed.
