2006-03-22 Michael Natterer <mitch@gimp.org> * tools/pdbgen/app.pl: removed support for invoke->pass_through. * tools/pdbgen/pdb/fileops.pdb: added a C utility function and call it from both register_load_handler() and register_magic_load_handler() instead of letting the generated invokers call each other. * app/pdb/fileops_cmds.c: regenerated.
