	* app/tools/gimptransformtool.[ch]: implemented transforming of
	paths. Cleaned up initialize() and button_press() to activate the
	tool correctly. Use the transform tool's CREATING state *only*
	before the first mouse click (when there is no grid displayed).
	Preview the active path while transforming. Cache the transform
	direction in the GimpTransformTool struct so we can switch it
	while previewing the path. Lots of path transform related changes
	and cleanup.
