	* configure.in: check for gdk-pixbuf-csource and allow to override
	it by setting the GDK_PIXBUF_CSOURCE environment variable.

	* themes/Default/images/Makefile.am: use the gdk-pixbuf-csource
	executable that was found at configure time.

	* app/base/levels.c: cosmetic change.

	* app/tools/gimplevelstool.c: allow to pick white, gray and black
	point for all channels. Allows for easy white-point balancing.

	* plug-ins/script-fu/scripts/3dTruchet.scm: restore the foreground
	color when the script is done (see bug #108473).
