OK, it turns out the previous script was totally wrong. Pickels coordinates are weird. The arguments tp pickel are from the top-left corner on the screen. The output is (Y,X) with coordinates from the top-right corner of the screen. Also, if you pass 0 0 0 0 as one of the rectangles it will take that rectangle as the whole screen, which is why I use 0 0 1 1 for the rectangle I don't care about.
