1.11: New phosphor trail options

After staring at videos of Spacewar!, the original digital video game, and its gorgeous radar scope-derived high-resolution, super-high-persistence display for far too long, I started to wonder just how legible a simulation of such slow phosphors would be on the Playdate.

Presenting: the XL and XXL ball trail options. They are not for everybody, and they were not even originally intended for human consumption, just prototyping. But my in-house playtesting crew actually preferred the XL option, so there you have it. XXL is a bit absurdly long, although still considerably shorter than the residual phosphor glow on the actual PDP-1 display, and is mostly included for novelty because it makes the paddle trails look pretty cool.
