/* 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}
