/* ION abstracts pushing pixels to the screen.
 *
 * There could be a single entry point, set_pixel, but setting pixels one by one
 * incurs quite a large overhead because you need to send the coordinate of each
 * pixel to the screen.
 *
 * Many displays support sending contiguous pixels without having to repeat the
 * pixel coordinates every time. We're therefore leveraging this capability
 * which results in a very consequent speedup (up to ~10x faster). */
