	* app/widgets/gimpviewrenderer.c (gimp_view_renderer_real_draw):
	if the surface has CAIRO_CONTENT_COLOR_ALPHA, render it on a
	checkerboard background.

	* app/widgets/gimpviewrenderergradient.[ch]: just draw the
	gradient with alpha-transparency instead of doing the blend on 
the
	checkerboard here.

	* app/widgets/gimpcolormapeditor.c: formatting.
