/* 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. */
