2003-05-08 Michael Natterer <mitch@gimp.org> * app/core/gimplayer.[ch]: removed "linked" member and API... * app/core/gimpitem.[ch]: ...and added it here. * app/core/core-enums.[ch] * app/core/gimpimage-undo-push.[ch]: changed layer_linked undo types and functions to be item_linked ones. * app/tools/gimpeditselectiontool.c * app/xcf/xcf-load.c * app/xcf/xcf-save.c * tools/pdbgen/pdb/layer.pdb: changed accordingly. * app/pdb/layer_cmds.c: regenerated. * app/widgets/gimplayertreeview.[ch]: removed "linked" icon and functions... * app/widgets/gimpitemtreeview.[ch]: and added them here. Setting channels or vectors to "linked" does nothing yet.
