2008-04-21 Michael Natterer <mitch@gimp.org> Move the shadow tiles from the image to the drawable. Fixes bug #100469. * app/core/Makefile.am * app/core/gimpdrawable-shadow.[ch]: new files implementing the shadow tiles. * app/core/gimpimage.[ch]: remove the shadow tile manager from the GimpImage struct. Remove gimp_image_get_shadow_tiles() and _free_shadow_tiles(). * app/core/gimpdrawable.[ch]: add the shadow tile manager here. Remove get_shadow_tiles() and merge_shadow(). Free the shadow tiles in finalize and when the drawable gets removed from the image. * app/core/gimpdrawable-brightness-contrast.c * app/core/gimpdrawable-color-balance.c * app/core/gimpdrawable-colorize.c * app/core/gimpdrawable-curves.c * app/core/gimpdrawable-desaturate.c * app/core/gimpdrawable-equalize.c * app/core/gimpdrawable-hue-saturation.c * app/core/gimpdrawable-invert.c * app/core/gimpdrawable-levels.c * app/core/gimpdrawable-operation.c * app/core/gimpdrawable-posterize.c * app/core/gimpdrawable-threshold.c * app/core/gimpimagemap.c: changed accordingly. Free the shadow tiles after using them. * app/plug-in/gimpplugin-cleanup.[ch]: add gimp_plug_in_cleanup_add_shadow() and _remove_shadow() which keep track of whether shadow tiles were created on behalf of a plug-in procedure. (gimp_plug_in_cleanup): free shadow tiles which were created but not destroyed by a plug-in procedure. * app/plug-in/gimpplugin-message.c (plug_in_handle_tile_request): call gimp_plug_in_cleanup_add_shadow() whenever a plug-in requests shadow tiles. * tools/pdbgen/pdb/drawable.pdb: use the new drawable shadow API. Add new procedure gimp-drawable-free-shadow. Call gimp_plug_in_cleaup_remove_shadow() when it gets called. * tools/pdbgen/pdb/image.pdb: deprecate gimp-image-free-shadow. Calling it has no effect any longer. * app/pdb/drawable-cmds.c * app/pdb/image-cmds.c * app/pdb/internal-procs.c * libgimp/gimpimage_pdb.[ch] * libgimp/gimpdrawable_pdb.[ch]: regenerated. svn path=/trunk/; revision=25510
