GetW()

I think the Help needs to explain what 'W' actually is. Anybody have a good diagram they could donate?
Quaternions and spatial rotation
w² = 1-x²-y²-z² to normalize the quaternion.
x,y,z are not the rotations of euler angles like RotateXXX() !!
Quaternions represent an orderless rotation in the 3d space (different from orderly Pitch,Yaw,Roll)
