   Do any of the various colorfunc routines have any random element
   in them? I looked quickly and couldn't find any. If this is the
   case, then surely it is more efficient to code this as:-

	 if (errline != errlast)
	 {
	   errlast = errline;
	   Image_get_col(image, in, errline);
	   (*colorfunc)(in, out, image_height, image_bpp, cmap, v);
	 }

   so that the colorfunc is only called once instead of repeatedly
   for the same input line.

   Might shave a bit off the processing time if the image is being
   expanded a lot.

True.  The runtime is dominated by the dither, but this would save a
bit of time.
