removed the brush outline members since we have no chance to really cache 

2003-07-24  Michael Natterer  <mitch@gimp.org>

	* app/tools/gimppainttool.[ch]: removed the brush outline members
	since we have no chance to really cache them without duplicating
	GimpPaintCore's brush change notification code.

	* app/paint/gimppaintcore.[ch]: added the outline here and really
	cache it this time. The paint_core doesn't create or use the
	outline but frees and NULLifies it whenever the brush changes.
