[gimp/soc-2011-seamless-clone2] app: don't use a GeglProcessor when we don't need a progress

[Clayton Walker <claytonw src gnome org>]

commit 24cdcdd96c5ed30c57436fd4504ebcb414b4fb81
Author: Michael Natterer <mitch gimp org>
Date:   Sat Mar 2 18:30:22 2013 +0100

    app: don't use a GeglProcessor when we don't need a progress
    
    Instead, use gegl_node_blit() directly which is more than ten times
    faster in gimp_gegl_apply_operation(). Patch from Massimo Valentini.
