Moved current point state to XrGState and dropped relative operators from XrPath. This is all in preparation for XrShowText, (which needs access to the current point)

Removed state from XrFiller that was redundant with state in XrPolygon. Fixed state update in XrStroker so that paths with multiple subpaths work. Simplified error-prone sorting in XrPenAddPoints. Renamed XrPenVertexTag to XrPenVertexFlag, (to allow for a single vertex that is the starting point for both the forward and reverse half-path).
