	* app/paint/gimppaintoptions.c: changed the "fade-length" and
	"gradient-length" minimum values to 0.0 for compatibility with
	the PDB API.

	* app/paint/gimppaintcore.c (gimp_paint_core_get_color_from_gradient):
	check that gradient_length > 0.0 before dividing by it.

	* plug-ins/gfig/gfig.c (gfig_paint_callback): push an undo group
	around the paint operations (bug #110446).
