	Made brushes upscalable by using scale_region. Downscaling still
	uses functions in app/base/brush-scale.c (because of better
	performance). Parametric brushes of course recalculates masks
	instead of using bitmap scaling. Fixes bug #65030.

	* app/core/gimpbrush.[ch]: Added a private scale_buf method which
	uses scale_region (with GIMP_INTERPOLATION_LINEAR) to scale its
	masks and pixmaps. Also added public virtual method scale_size to
	GimpBrush (overridden by GimpBrushGenerated) which calculates the
	buffer sizes for a given brush scaled with a given scale.

	* app/core/gimpbrushgenerated.c: Implemented the new scale_size
	method inherited from GimpBrush, and modified
	gimp_brush_generated_calc to use this helper function.

	* app/tools/gimppaintoptions-gui.c (gimp_paint_options_gui): Made
	the brush Scale-slider logarithmic.

	* app/paint/gimppaintoptions.c (gimp_paint_options_class_init):
	Changed Scale scale to [0.0, 10.0].

	* app/paint/gimpbrushcore.c:
	(gimp_brush_core_calc_brush_size): Refactored 'get brush size' code
	to where it belongs, in GimpBrush-classes, and allowed scales
	larger than 1.0.
