- Add projector light textures.
- Tweak the flying forklift's dynamic light and particles to be more noticeable.
- Add bullet impact particles with collision against level geometry
(using a generated SDF).
- Don't use fixed FPS and disable interpolation to make particles smoother
(trails aren't used, so fixed FPS isn't strictly needed).
- Add proximity fade to some particles to smooth out the transition
with solid geometry.
- Fix some particles being shaded when they should be unshaded.
- Reduce crosshair size to be more subtle while aiming.
