+/* winPushPixels -- squeegees the fill style of pGC through pBitMap

+ * be bigger) which is placed on the drawable at xOrg, yOrg.  Where a 1 bit
+ * is set in the bitmap, the fill style is put onto the drawable using
+ * the GC's logical function. The drawable is not changed where the bitmap
+ * has a zero bit or outside the area covered by the stencil.
+
+WARNING:
+    this code works if the 1-bit deep pixmap format returned by GetSpans
+is the same as the format defined by the mfb code (i.e. 32-bit padding
+per scanline, scanline unit = 32 bits; later, this might mean
+bitsizeof(int) padding and sacnline unit == bitsizeof(int).)
