2007-11-05 Michael Natterer <mitch@gimp.org> * app/core/gimpcurve.[ch]: don't recalculate the curve if the data object is frozen. Recalculate on thaw instead. Made gimp_curve_calculate() private and emit some GimpData::dirty signals where appropriate. * app/tools/gimpcurvestool.c * app/widgets/gimpcurveview.c * tools/pdbgen/pdb/color.pdb: changed accodingly (connect to "dirty" instead of "notify" and added some freeze/thaw where approproate). * app/pdb/color_cmds.c: regenerated. svn path=/trunk/; revision=24063
