2005-04-16 Sven Neumann <sven@gimp.org> Applied a patch (with minor modifications) from Karine Delvare that makes it possible to choose between various ways to remove color from a drawable (bug #155507): * libgimpbase/gimpbaseenums.h: added new enum GimpDesaturateMode. * libgimpbase/gimpbaseenums.c * libgimp/gimpenums.c.tail * plug-ins/pygimp/gimpenums.py * tools/pdbgen/enums.pl: regenerated. * app/core/gimpdrawable-desaturate.[ch]: implement other formulas to remove colors from a drawable. * tools/pdbgen/pdb/color.pdb: let gimp_desaturate() call gimp_drawable_desaturate() with GIMP_DESATURATE_LIGHTNESS so that it behaves like it always did. * app/pdb/color_cmds.c: regenerated. * app/dialogs/Makefile.am * app/dialogs/desaturate-dialog.[ch]: new files that define a simple dialog to choose a mode for desaturation. * app/actions/drawable-actions.[ch]: use the new dialog.
