/**
Modifications to twgl.js:
MB - added 6x2 stereo cubemap layout to 'setTextureFromElement()', use 'shift=1' to select offset
MB - added 'twgl.m4.fromRotationTranslation()' for minimal quaternion webVR support (borrowed from Gregg Tavares's glmatrix library)
MB - added 'twgl.m4.eularToQuat()' to convert onDeviceOrientation input to quaternion
MB - added option 'shrink'. Resize cubemap destination canvas to allow for bad GPU's (ie. where max cube map texture size = 1024)
