Fixed depth range of WebVR projection matrices

Fixed depth range of WebVR projection matrices

Accidentally used a matrix that assumed a [0, 1] depth range (which is what D3D
uses) instead of OpenGL's [-1, 1] range. This effectively cut the depth
precision in half.

Anyone want to rubber-stamp my this minor math tweak?
