I don't have a definitive answer, but to me it looks like it's a very simple checkerboard dither for the outermost layer - you can see it in curved icons, where there aren't any pixels in the outermost layer in areas that coincide with a 45 degree line of "blank" pixels in the checkerboard. So it looks like it would be a case of placing a pixel if the LSB of the X value matches the LSB of the Y value, otherwise leave it as colour 0. That's where I'd start anyway...
