Fixing some odds and ends, updating the name of the game to "Blue"
Automatically launch into the ocean level.
Added a sphere player model. Beautiful. Now I want to add Viewback so I can tweak parameters more easily.
New camera position and player movement values. Hook up viewback so I can change values on the fly. Implement a new movement system that accelerates the player and drags to a stop, suggesting motion through a fluid.
Add a dust particle system, with some extensions to the particle system to support perf improvements by only allowing particles to spawn near the player, and fading them out when they're too far. This particle system needs a lot more perf improvements, but that will come later.
A skybox, for maximum greyness.
Optimization: By swapping dead particles to the end of the particle list, we get perf wins on a number of fronts. We don't have to iterate dead particles, so we get cache wins and less processing, and insertion time is now constant since we always know where there is a dead particle to replace.
