-/* scanline filling for monochrome frame buffer
- written by drewry, oct 1986
-
- 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}
