Hi there,

we need a a simple way to save the current clip path. This should happen
without saving the whole graphics context.

This feature is required, since we want use the PostScript clipping facility
to realize:

	1) filling arbitraily shaped objects with hatch styles (avoiding to use
	the time consuming operator "setscreen", that may define an hatch look
	alike pattern);

	2) local clipping in an composed document (i.e., a document handler
	provides for some space within which the image represented by the
	piece of PostScript code is to be imaged but still using clipping
	locally to build this image (e.g., a frame displaying the graph of a
	function versus the decoration -axes, legend etc.- around)).
