2004-03-20 Simon Budig <simon@gimp.org> * app/core/gimpundo.[ch]: Make it possible to refresh the preview of an undo step. * app/tools/gimpeditselectiontool.c * app/widgets/gimpitemtreeview.c * app/widgets/gimplayertreeview.c: refresh the preview when compressing undos. This ensures that the last preview in the undo history always reflects the current state of the image.
