gimp r28069 - in trunk: app/actions menus

[martinn svn gnome org]

Author: martinn

New Revision: 28069
URL: http://svn.gnome.org/viewvc/gimp?rev=28069&view=rev

Log:
Add a Show Image Graph item to the Debug menu

Add a Show Image Graph item to the Debug menu that creates a new image
showing the GEGL graph for the image. Would benefit from an enhanced
gegl:introspect op with a clearer graph, but still quite interesting
in its current shape.
