2002-02-26 Michael Natterer <mitch@gimp.org> * app/app_procs.c: make absolute paths out of relative ones passed on the commandline so the GimpImagefiles can generate previews. * app/gui/Makefile.am * app/gui/drawable-commands.[ch]: new files implementing menu callbacks which work not just on layers. * app/gui/layers-commands.[ch]: removed them here. Cleanup. * app/gui/menus.c: changed accordingly. * app/gui/brushes-commands.c * app/gui/channels-commands.c * app/gui/vectors-commands.c: cleanup. Added macros to get rid of code duplication.
