2003-05-13 Michael Natterer <mitch@gimp.org> * app/core/gimpitem.[ch]: added "gboolean clip_result" to GimpItem::flip(). * app/vectors/gimpvectors.c * app/tools/gimpfliptool.c: changed accordingly. * app/core/gimpdrawable.c: implement GimpItem::flip() and GimpItem::transform(). * app/core/gimpchannel.c * app/core/gimplayer.c: chain up in flip() and transform() and do only the layer/channel specific stuff here. * app/core/gimpdrawable-transform.[ch]: fixed indentation. (gimp_drawable_transform_tiles_flip): added "gboolean clip_result" and warn that it is not yet implemented. (gimp_drawable_transform_tiles_affine): when transforming a channel set bg_color to transparent. Clip channels (but not layer masks) only if the passed tiles have bpp == 1 (the channel is unfloated). (gimp_drawable_transform_affine): clip all unfloated channels. * app/core/gimpitem-linked.[ch]: added gimp_item_linked_get_list() utility function to avoind iterating all layers/channels/vectors in all functions. * app/tools/gimptransformtool.c: clip all unfloated channels. The clipping fixes above together fix bug #112858.
