Script Preparation code:

function cell1(width, height, cols, rows, x, y) {
    // mainly meant for the drawImage function (spread at arguments[1])
    let w = height / rows,
        h = width / cols
    return Uint16Array.of(w * x % width, h * y % height, w, h)
}

function cell2(width, height, cols, rows, x, y) {
    // mainly meant for the drawImage function (spread at arguments[1])
    let w = height / rows,
        h = width / cols
    return [w * x % width, h * y % height, w, h]
