 * Note to future maintainers:  XDrawArc does NOT batch successive PolyArc
 * requests into a single request like XDrawLine, XDrawPoint, etc. We don't
 * do this because X_PolyArc applies the GC's join-style if the last point in
 * one arc coincides with the first point in another. The client wouldn't
 * expect this and would have no easy way to defeat it.
