2006-05-03 Michael Natterer <mitch@gimp.org> Made an object out of the plug-in struct. Also change refcounting considerably: - gimp_plug_in_open() adds a reference that is only dropped by gimp_plug_in_close(). - temporarily ref the plug-in while handling messages. - remporarily ref the plug-in while a recursive main loop is running. - each caller of gimp_plug_in_new() also unrefs the plug-in before returning, the only reference that persists across functions (that keeps the plug-in alive) is the one added by open(). * app/plug-in/plug-in.[ch] * app/plug-in/plug-in-context.[ch] * app/plug-in/plug-in-message.[ch] * app/plug-in/plug-in-progress.[ch]: removed these files... * app/plug-in/gimpplugin.[ch] * app/plug-in/gimpplugin-context.[ch] * app/plug-in/gimpplugin-message.[ch] * app/plug-in/gimpplugin-progress.[ch]: ...and added here as GObject. * app/plug-in/plug-in-proc-frame.[ch]: removed... * app/plug-in/gimppluginprocframe.[ch]: ...and added with a namespace. * app/plug-in/Makefile.am * app/plug-in/plug-in-types.h * app/plug-in/gimppluginmanager-call.c * app/plug-in/gimppluginmanager-file.c * app/plug-in/gimppluginmanager.[ch] * app/pdb/gimppluginprocedure.c * app/pdb/gimptemporaryprocedure.c * app/pdb/gimptemporaryprocedure.h * tools/pdbgen/pdb/context.pdb * tools/pdbgen/pdb/drawable.pdb * tools/pdbgen/pdb/help.pdb * tools/pdbgen/pdb/message.pdb * tools/pdbgen/pdb/plug_in.pdb * tools/pdbgen/pdb/progress.pdb * tools/pdbgen/pdb/undo.pdb: changed accordingly. * app/pdb/context_cmds.c * app/pdb/drawable_cmds.c * app/pdb/help_cmds.c * app/pdb/message_cmds.c * app/pdb/plug_in_cmds.c * app/pdb/progress_cmds.c * app/pdb/undo_cmds.c: regenerated.
