Don't assume any more that the gtkwidget.c code will queue a redraw on us

1999-02-05  Owen Taylor  <otaylor@gtk.org>

	* gtk/gtk[hv]paned.c (gtk_[hv]paned_size_allocate):
	Don't assume any more that the gtkwidget.c code
	will queue a redraw on us during a size_allocate -
	queue clear/draws as appropriate for our groove.
