Splats coming out of drains have a weird frustum check problem that makes them

1. invisible/not rendering and
2. untargetable
   during their first moments of life (about 2-3 seconds)

This is jarring pop-in, but also a mechanical imperfection and not just cosmetic.

It's annoying me greatly, so figure out why the render bounds are failing frustum checks and fix this nonsense.

Derpy bounding box issue fixed :D
