Sprite projectiles aren't added to/removed from ScreenMap.

Checked on Bullet, Missile and GravityBomb at least, neither gets the screenmap updates so they don't end up benefitting from the don't-render-outside-of-screen changes.

This is not a bug, the feature simply hasn't been completed yet.

The reason why I didn't migrate them yet is basically because I wasn't sure how to calculate the screen bounds of contrails, since they can follow curves.
