	* app/widgets/widgets-enums.h: added a new enum to specify how to
	display histograms.

	* app/widgets/widgets-enums.c: regenerated.

	* app/widgets/gimphistogramview.[ch]: added a scale property and
	made channel a property. Added support for linear histograms based
	on a patch from Akkana (see bug #72951).

	* app/widgets/gimphistogrambox.c: redraw the gradient when the
	histogram view notifies it that the displayed channel has changed.

	* app/tools/gimphistogramtool.c: added a menu to configure the
	histogram scale.
