2005-09-25 Michael Natterer <mitch@gimp.org> * app/actions/plug-in-actions.c * menus/image-menu.xml.in: get rid of Filters/Effects because it doesn't mean anything. Added Filters/Generic and Filters/Combine back instead. Not perfect either but more meaningful. * plug-ins/common/depthmerge.c * plug-ins/common/film.c: -> Filters/Combine * plug-ins/common/convmatrix.c * plug-ins/common/vpropagate.c: -> Filters/Generic * plug-ins/script-fu/scripts/erase-rows.scm: -> Filters/Distorts * plug-ins/script-fu/scripts/predator.scm: -> Filters/Artistic

; the view the predator had in the movies. ie, kind of a thermogram
|

; type of thing. Works best on colorful rgb images.
