2003-02-11 Michael Natterer <mitch@gimp.org> * app/core/gimpitem.[ch]: added new virtual function duplicate() as replacement for all gimp_*_copy() functions. * app/core/gimpchannel.[ch] * app/core/gimpdrawable.[ch] * app/core/gimplayer.[ch] * app/core/gimplayermask.[ch] * app/vectors/gimpvectors.[ch]: replaced public copy() functions by duplicate() implementations. * app/text/gimptextlayer.c: added a duplicate() implementation. * app/widgets/gimpitemlistview.[ch]: removed the "copy_item_func" and simply call gimp_item_duplicate(). * app/undo.c * app/core/gimpimage-duplicate.c * app/core/gimpimage-mask.c * app/core/gimpimage-qmask.c * app/gui/channels-commands.c * app/gui/dialogs-constructors.c * app/gui/layers-commands.c * app/gui/vectors-commands.c * app/widgets/gimptoolbox.c * tools/pdbgen/pdb/channel.pdb * tools/pdbgen/pdb/layer.pdb * tools/pdbgen/pdb/selection.pdb: changed accordingly. * app/pdb/channel_cmds.c * app/pdb/layer_cmds.c * app/pdb/selection_cmds.c: regenerated.
