New Revision: 25533
URL: http://svn.gnome.org/viewvc/gimp?rev=25533&view=rev

Log:
* app/tools/gimpgegltool.c: (gimp_get_subtype_classes),
(gimp_gegl_tool_compare_operation_names), (gimp_get_geglopclasses),
(gimp_gegl_tool_dialog): made the GEGL tool only show ops from
relevant categories, the list of relevant categories is hard coded
for now.
