	* app/gdisplay_ops.c (gdisplay_shrink_wrap): block all canvas
	events while resizing the display so the standard canvas "expose"
	and "configure" handlers are not called.
	This optimization is valid because shrink_wrap's caller has to do
	a full recalculation and expose of the gdisplay anyway.
	For the same reason, I removed the calls to gdisplay_expose_full()
	and bounds_checking() from shrink_wrap.

	This should also fix the double exposes Austin reported some time
	ago. I hope it does not re-break yesterday's fix :)

	* app/gdisplay_ops.[ch]: removed unused function
	gdisplay_resize_image().

	* app/scale.c (resize_display): do a full expose if one of the
	"resize_display" or "redisplay" parameters is TRUE.
