- * Filled solid arcs, based on cfbfillarc.c.
- *
- * Fill arc using calls to low-level span fill. Because the math for
- * each span can be done concurrently with the drawing of the span
- * with a graphics coprocessor operation, this is faster than just
- * using miPolyFillArc, which first calculates all the spans and then
- * calls FillSpans.
- *
- * Clipped arcs are dispatched to FillSpans.
