	Wishlist item #57812:

	* app/core/gimpimage.[ch]: added a progress_callback to
	gimp_image_scale().

	* app/gui/gui.c
	* app/gui/image-commands.c
	* app/gui/resize-dialog.h
	* tools/pdbgen/pdb/image.pdb: changed accordingly.

	* app/core/gimp.[ch]: found that gimp->busy needs to be a counter,
	not a boolean, so nested calls work.

	* app/pdb/image_cmds.c: regenerated.
