2003-12-08 Michael Natterer <mitch@gimp.org> * tools/pdbgen/pdb/image.pdb: marked gimp_image_add_layer_mask() and gimp_image_remove_layer_mask() as deprecated. Didnn't remove them from the PDB because the new functions' signature differs and they are used very often in scripts, but removed them from the libgimp C wrappers. * tools/pdbgen/pdb/layer.pdb: added gimp_layer_add_mask() and gimp_layer_remove_mask(). * libgimp/gimpcompat.h: added compat cruft. * app/pdb/image_cmds.c * app/pdb/internal_procs.c * app/pdb/layer_cmds.c * libgimp/gimpimage_pdb.[ch] * libgimp/gimplayer_pdb.[ch]: regenerated. * libgimp/gimpexport.c * plug-ins/common/curve_bend.c * plug-ins/common/psd.c * plug-ins/pygimp/pygimp-image.c * plug-ins/script-fu/scripts/3d-outline.scm * plug-ins/script-fu/scripts/alien-neon-logo.scm * plug-ins/script-fu/scripts/blended-logo.scm * plug-ins/script-fu/scripts/burn-in-anim.scm * plug-ins/script-fu/scripts/carve-it.scm * plug-ins/script-fu/scripts/carved-logo.scm * plug-ins/script-fu/scripts/chrome-it.scm * plug-ins/script-fu/scripts/chrome-logo.scm * plug-ins/script-fu/scripts/coolmetal-logo.scm * plug-ins/script-fu/scripts/crystal-logo.scm * plug-ins/script-fu/scripts/fade-outline.scm * plug-ins/script-fu/scripts/frosty-logo.scm * plug-ins/script-fu/scripts/image-structure.scm * plug-ins/script-fu/scripts/news-text.scm * plug-ins/script-fu/scripts/rendermap.scm * plug-ins/script-fu/scripts/slide.scm * plug-ins/script-fu/scripts/sota-chrome-logo.scm * plug-ins/script-fu/scripts/speed-text.scm * plug-ins/script-fu/scripts/starburst-logo.scm * plug-ins/script-fu/scripts/textured-logo.scm * plug-ins/script-fu/scripts/weave.scm * plug-ins/script-fu/scripts/xach-effect.scm * plug-ins/xjt/xjt.c: changed accordingly. 2003-12-08 Michael Natterer <mitch@gimp.org> * libgimp/libgimp-sections.txt * libgimp/tmpl/gimpimage.sgml * libgimp/tmpl/gimplayer.sgml: follow layer mask API change.
