	* app/core/gimpimage-mask.[ch] (gimp_image_mask_boundary)
	* app/core/gimplayer-floating-sel.[ch] (floating_sel_boundary):
	return const BoundSeg arrays because they are cached and not newly
	allocated.

	* app/tools/gimpdrawtool.[ch] (gimp_draw_tool_draw_boundary):
	take const BoundSeg arrays.

	* app/display/gimpdisplayshell-selection.c
