2002-08-20 Michael Natterer <mitch@gimp.org> Make sure the selection (gimpimage-mask.c) functionality is really built *on top* of the GimpChannel functionality: * app/undo.[ch]: renamed undo_push_image_mask() to undo_push_mask() and generalized it's API to take a GimpChannel param so undos can be pushed for channels which are not the image's selection. Simplified the API and added code which copies the region of interest instead of leaving this to callers. * app/undo_types.h: s/IMAGE_MASK_UNDO/MASK_UNDO/ * app/undo_history.c: changed accordingly. * app/core/gimpchannel.[ch]: don't #include "gimpimage-mask.h". Changed gimp_channel_push_undo() to really push a channel undo, not a selection undo. Added "gboolean push_undo" params to all functions which are called from gimpimage-mask.c. Various cleanups and optimizations. Added /*< proxy-foo >*/ stuff to the header so we export just the struct itself to libgimpproxy. Added accessors gimp_channel_[get|set]_show_masked(). * app/core/gimpimage-mask.[ch]: renamed gimp_image_mask_undo() to gimp_image_mask_push_undo(). Call it before calling GimpChannel functions which modify the mask, also call all GimpChannel functions with push_undo = FALSE. Emit gimp_image_mask_changed() after each operation instead of calling it in gimp_image_mask_invalidate(). Removed gimp_image_mask_none() because it is the same as gimp_image_mask_clear(). General cleanup. * app/core/gimpimage-mask-select.c * app/core/gimpimage-qmask.c: changed accordingly. * app/core/gimpedit.c: call gimp_image_mask_clear(), not gimp_channel_clear (gimp_image_get_mask()). * app/core/gimpimage-crop.c * app/core/gimpimage-resize.c * app/core/gimpimage-scale.c: call gimp_image_mask_changed() * app/gui/channels-commands.c * app/gui/select-commands.c * app/tools/gimptexttool.c * tools/pdbgen/pdb/channel.pdb * tools/pdbgen/pdb/selection.pdb: follow GimpChannel and gimp_image_mask* API changes. * app/pdb/channel_cmds.c * app/pdb/selection_cmds.c * libgimpproxy/gimpchannel.h: regenerated. Unrelated: * app/core/gimpimage.c: call gimp_drawable_push_undo() instead of undo_push_image() directly.
