2001-04-19 Michael Natterer <mitch@gimp.org> * app/Makefile.am * app/brush_header.h * app/pattern_header.h * app/desaturate.[ch] * app/equalize.[ch] * app/invert.[ch]: removed. * app/gimpbrush-header.h * app/gimppattern-header.h * app/gimpdrawable-desaturate.[ch] * app/gimpdrawable-equalize.[ch] * app/gimpdrawable-invert.[ch]: new files. * app/gui/commands.c: put some stuff from desaturate, equalize and invert here. While it's ok to check the drawable type in the callback, this is the wrong place for PDB wrappers. * app/gimpbrush.c * app/gimpbrushpipe.c * app/gimplayer.c * app/gimppattern.c * app/pdb/color_cmds.c * plug-ins/common/gbr.c * plug-ins/common/gih.c * plug-ins/common/pat.c * po/POTFILES.in * tools/pdbgen/pdb/color.pdb: changed accordingly.
