+ these routines all clip. they assume that anything that has called
+them has already translated the points (i.e. pGC->miTranslate is
+non-zero, which is howit gets set in mfbCreateGC().)
+
+ the number of new scnalines created by clipping ==
+MaxRectsPerBand * nSpans.
+
+ FillSolid is overloaded to be used for OpaqueStipple as well,
+if fgPixel == bgPixel.
+
+
+ FillTiled is overloaded to be used for OpaqueStipple, if
+fgPixel != bgPixel. based on the fill style, it uses
+{RotatedPixmap, gc.alu} or {RotatedPixmap, PrivGC.ropOpStip}
