use gem::prelude::*;

let mut red_box_50x50 = vec![Abgr8888::from_abgr(0xFF, 0x00, 0x00, 0xFF); 50 * 50];

// Make a semi-transparent blue box in the middle of the image
for y in 0..50 {
    for x in 0..50 {
        if (10..40).contains(&x) && (10..40).contains(&y) {
            red_box_50x50[y * 50 + x] = Abgr8888::from_abgr(0x7F, 0x7F, 0x00, 0xFF);
        }
    }
