app/core/Makefile.am new files containing gimp_drawable_apply_operation() 

2008-01-02  Michael Natterer  <mitch@gimp.org>

	* app/core/Makefile.am
	* app/core/gimpdrawable-operation.[ch]: new files containing
	gimp_drawable_apply_operation() which applies a gegl operation
	to a drawable's selected pixels using shadow tiles. Will soon
	be used in more places than just invert.

	* app/core/gimpdrawable-invert.c: use it here, makes
	gimp_drawable_invert() a 3-liner.
