	* app/tools/gimprotatetool.c (roatate_angle_changed): compare the
	old and new angle using an epsilon of 0.0001 degrees so we don't
	get double "angle changed" because of rounding foobar.

	* app/tools/gimptransformtool.c: made GimpTransformTool subclasses
	which don't use the grid (namely the flip tool) work correctly
	again by looking at transform_tool->use_grid more often.
