    app: add gimp_brush_core_get_brush_pixmap()
    
    In GimpBrushCore, replace the private
    gimp_brush_core_transform_pixmap() function with a public
    gimp_brush_core_get_brush_pixmap() function, which, similarly to
    gimp_brush_core_get_brush_mask(), returns the transformed brush
    pixmap, and can be used by subclasses.
