You don’t really need this thing as you’ve got explicit bounds for the view, and the LEDs will draw on top of the black background anyway. But if you insist on using it, you’re better off putting it behind the screen rather than on top to ensure it doesn’t slightly crop the bottom of the screen when the floating point view coordinates are quantised to whole pixel values.

Would it be a good idea to add text labels for the LEDs? As it is, there are three identical-looking round LEDs, the function of which won’t be clear without examining the source. Also, the outputs corresponding to these don’t appear to actually be hooked up?
