Description Owen Taylor 2001-05-11 20:18:55 UTC 
Exposure events are generated for calls to gdk_window_invalidate_region()
and also by the predictive exposure code in gdkgeometry-x11.c without
regard to GDK_EXPOSURE_MASK.

This could be considered a bug, though similar things happened in
GTK+-1.2 when GTK+ would generate synthetic exposure events for
widgets without draw() handlers...
