	* app/display/Makefile.am
	* app/display/gimpdisplayshell-marching-ants.h: removed this file.

	* app/display/gimpcanvas.[ch]: generalized creation of GCs. Added
	styles for drawing the selection and layer boundaries. Also added
	support for changing stipple masks as was used by an older
	implementation of the marching ants (see below).

	* app/display/gimpdisplayshell-callbacks.c
	* app/display/gimpdisplayshell.c: don't create the Selection when
	the canvas is realized but only once when it is created.

	* app/display/gimpdisplayshell-selection.[ch]: removed all GC code
	and draw by means of GimpCanvas. Also resurrected a different
	implementation of the marching ants that was lost since 1.2
	(#undef USE_DRAWPOINTS).
