Use the previously unused window->need_resize flag to mark if a window's

Mon May 11 21:04:51 1998  Owen Taylor  <otaylor@gtk.org>

	* gtk/gtkwindow.c (gtk_real_window_move_resize): Use the
	previously unused window->need_resize flag to mark if a window's
	descendents changed size while the window was not visible. In this
	case, when the window becomes visible, we reallocate everything,
	since we didn't keep track of what actually changed.

	(Fixes bug where changing the popdown strings of a
	combo to something of the same length caused them to
	blank out, as reported by Todd Dukes <tdukes@ibmoto.com>)
