I am trying to make an 1 bit per pixel PNG image, but I want the colors to be pure black and white. When setting bit depth to 1, it either uses a palette that may contain grayscales, which looks really bad when tiled, or it does thresholding without dithering, which is also suboptimal.

So what I'd like to be able to do is either specify a fixed palette, or do dithering without using a palette at all, but I've been told by the sharp people that libvips can't do this.
