By calling hres.set(x, y, state) you can set a pixel at that x, y position to either be the foreground, or the background color. The x and y positions are the exact pixel location you'd like.
This allows for a theoretical maximum resolution of 320 by 200. This is achieved by using the Unicode braille characters. To get the current "hres" resolution you take the screens current x resolution and multiply by 2, and you take the screens current y resolution and multiply by 4.
There may be bugs, and things may behave oddly if you try to "turn off" a pixel that was not "on" in the first pl
