+	(_XrPathBounds): New support for computing the bounding box of a
+	path. Currently used internally, (for computing the size of the
+	clip surface), and not exported publically.

+	* src/xrgstate.c (_XrGStateStroke): Implemented clip support for
+	strokes.
+	(_XrGStateClip): New _XrGStateClip function fills the current path
+	onto the gstate->clip surface.
+
+	* src/xr.c (XrClip): Added preliminary/experimental clip
+	functionality. The current implementation only clips stroked
+	elements, (not fills, images, or text). It's alway quite
+	inefficeient.
