	* app/widgets/gimphistogramview.[ch]: added properties "border-width"
	and "subdivisions". Fixed rendering (it off-by-one worked just
	accidentially because border-width was hardcoded to 1).

	* app/widgets/gimphistogrambox.c: use the histogram view's border
	width for the color area below the histogram. Conect to the right
	signal to update the area. Added (#ifdef DEBUG_VIEW) debugging
	spinbuttons to change the histogram view's new properties on the
	fly.
