+/* 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. */
