The start screen, integrated. Also just committed a reorganisation/cleanup of the code, splitting it into more functions rather than the previous enormous loop. This allows me to get nice call graphs with KCachegrind, in which I confirm that my whole screen drawing is just under 4000 cycles on average.
It makes it faster than it takes the ray to reach the top-left of the screen during vertical blanking (4550 cycles) and leads to no tearing or flickering!
