Generalising how basic float based view adjustments are stored and handled.
Cleaning up this test so it can be merged. Adds separate matrix adjustment (MatrixSimplePlusOrthoReproject.h) that handles perspective the default stereo way and re-projects orthographically projected stuff using perspective. Used in source engine games only at the moment. Defaults put the HUD ~2m in front of player. Closes #1.
