2004-04-13 Michael Natterer <mitch@gimp.org> Moved the calls to floating_sel_relax()/rigor() from various places to two single spots in the core where they are actually needed. Fixes bug #138356 (which was caused by the projection being triggered in the middle of changing the floating selection's size or the size of the drawable it is attached to). This commit effectively removes floating selection fiddling from the core's public API. * app/core/gimpdrawable.[ch] (gimp_drawable_has_floating_sel): new function which returns TRUE if there is a floating selection attached to the drawable. * app/core/gimpdrawable.c (gimp_drawable_translate) (gimp_drawable_set_tiles_full): if the drawable *has* a floating selection, relax/rigor it before/after modifying the drawable. * app/core/gimplayer.c (gimp_layer_translate) (gimp_layer_set_tiles): if the layer *is* the floating selection, relax/rigor it before/after modifying it. * app/core/gimpdrawable-transform.c * app/core/gimpimage-convert.c * app/core/gimpimage-crop.c * app/core/gimpimage-flip.c * app/core/gimpimage-resize.c * app/core/gimpimage-rotate.c * app/core/gimpimage-scale.c * app/gui/layers-commands.c * app/tools/gimpeditselectiontool.c * tools/pdbgen/pdb/layer.pdb: removed calls to floating_sel_rigor()/relax() all over the place. Also removed lots of undo groups which are obsolete now. * app/pdb/layer_cmds.c: regenerated.
