Yes, I'd be delighted if you did. I wasn't sure how to modify your 
library. I'm guessing something like this:

...
var screenWidth = 640;
var screenHeight = 400;
var blockWidth = screenWidth / 40;
var blockHeight = screenHeight / 40;
...
function plot(x, y) {
    rect(x * blockWidth, y * blockHeight,
        blockWidth, blockHeight)
}

function hlin(x1, x2, y) {
    if (x1 <= x2) rect(x1 * blockWidth, y * blockHeight,
        (x2 - x1 + 1) * blockWidth, blockHeight);
    else rect(x2 * blockWidth, y * blockHeight,
        (x1 - x2 + 1) * blockWidth, blockHeight);
}

function vlin(y1, y2, x) {
    if (y1 <= y2) rect(x * blockWidth, y1 * blockHeight,
        blockWidth, (y2 - y1 + 1) * blockHeight);
    else rect(x * blockWidth, y2 * blockHeight,
        blockWidth, (y1 - y2 + 1) * blockHeight);
}
