	Enable brush scaling for smudge (but only before, not while
	painting). Fixes bug #471348.

	* app/paint/gimpbrushcore.[ch] (struct GimpBrushCoreClass): rename
	member "use_scale" to "handles_scaling_brush".

	(gimp_brush_core_calc_brush_scale): apply pressure scale only if
	both "handles_scaling_brush" and "use_pressure" are TRUE, and
	apply the scaling from the options unconditionally.

	(gimp_brush_core_get_paint_area): don't re-fetch core->scale if
	"handles_scaling_brush" is FALSE to keep the brush from scaling
	*while* painting.

	(gimp_brush_core_create_bound_segs): use the brush scale from the
	options unconditionally since that's always used now.

	* app/paint/gimpsmudge.c (gimp_smudge_brush_coords): use
	gimp_brush_scale_size() to figure the accum_buffer's size instead
	of using the brush mask's size directly.

	* app/tools/gimppaintoptions-gui.c (gimp_paint_options_gui): show
	the brush scale controls for all brush tools.
