Changed refresh order so that window-less widgets
don't get overdrawn anymore,
Prevent GTK from filtering our supposedly unneeded
expose events,
Block all expose calls if a resize is requested and
do a full redraw then, thus removing flicker and
behaving like wxMSW,
Moved some doubled expose and draw code from GtkPizza
to the respective callbacks in window.cpp,
Set idle priority to a higher value (which should
indicate a lower priority if I interpret glib.h
correctly) but the desired side-effect didn't
really show up.
