2004-08-03 Michael Natterer <mitch@gimp.org> * app/core/gimpimage-undo.[ch] (gimp_image_undo_can_compress): new function which checks if undo compression is possible: (1) is the image dirty? Fixes bug #148853. (2) is redo stack empty? (3) do both the passed undo object_type and undo_type match the top undo item? Consistently name the GType and GimpUndoType passed to undo functions "object_type" and "undo_type" to avoid confusion. * app/actions/layers-commands.c * app/tools/gimpeditselectiontool.c * app/tools/gimptexttool.c * app/widgets/gimpitemtreeview.c * app/widgets/gimplayertreeview.c: use the new utility function instead of checking the above conditions manually.
