2001-12-13 Michael Natterer <mitch@gimp.org> * app/core/gimp.[ch]: made gimp->global_buffer a GimpBuffer, not TileManager. * app/core/gimpbuffer.[ch]: added a "gboolean copy_pixels" to gimp_buffer_new(). * app/core/gimpimage-new.c * app/core/gimpedit.[ch] * app/core/gimpimage-qmask.c * app/widgets/gimpbufferpreview.c * app/widgets/gimpbufferview.c * app/widgets/gimpcontainerview-utils.c: chaned accordingly, don't include "base/tile-manager.h". * app/core/gimpdrawable.[ch]: added gimp_drawable_copy(). * app/core/gimpchannel.[ch] * app/core/gimplayer.[ch] * app/core/gimplayermask.[ch]: use it in gimp_[channel|layer|layer_mask]_copy(), added "GType new_type" as paramater to all of them. * app/core/gimpimage-duplicate.c * app/gui/channels-commands.c * app/gui/edit-commands.c * app/gui/layers-commands.c * app/widgets/gimpchannellistview.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. * app/core/gimplayer.[ch]: removed the "layer_type" parameter from gimp_layer_new_from_tiles() because it always needed to be equal to gimp_image_base_type_with_alpha() of the passed image. * app/core/gimpdrawable-transform.c * app/core/gimpedit.c * app/core/gimpimage-mask.c: cahanged accordingly. * app/core/gimpimage.[ch]: added some new GIMP_IMAGE_TYPE_FOO() marcos to get rid of magic values like "pixels = 3" all over the place. * app/core/gimplayer.[ch]: added gimp_layer_new_from_drawable() which creates a layer from an other image's drawable. * app/core/gimpimage-convert.[ch]: made the RGB and GRAY converters public to use them above, use the new GIMP_IMAGE_TYPE() macros. * app/display/gimpdisplayshell-dnd.c * app/gui/toolbox.c: removed tile manager stuff and use the new functions. * app/widgets/gimpdrawablelistview.[ch]: added a "convert_drawable_func" which is used to handle drops from other images. * app/widgets/gimpdrawablelistitem.c * app/widgets/gimplayerlistitem.c * app/widgets/gimplistitem.[ch]: implemented DND of layers between images using gimp_layer_new_from_drawable(). * app/gui/dialogs-constructors.c: changed accordingly.
