Cameras can render even when they are not in the scenemanager or onAnimate didn't get called for example because they are their parent are invisible.
So let's be safe and add another call to updateAbsolutePosition(). Some cost, but usually we don't have that many rendering cameras, so shouldn't matter (if it ever matters I suppose we could override OnAnimate and add a flag if it _was_ animated since last render call. Maybe that's even useful in general for SceneNodes?).
Similar CSceneNodeAnimatorCameraFPS was using getAbsolutePosition which was only updated after animators, so it was one frame behind.
And documented ICameraSceneNode functions a bit. Especially updateMatrices is a bit of a confusing name unfortunately.

- allow ICameraSceneNode to accept any values and correct in buildCameraLookAtMatrixLH with normalize_camera_direction.
if disabled defaults to the current v1.9 normalize
b) add initial Rotation to MayaCamera Constructor default 0,0
c) switchToMayaCamera in Examples. Clones FPSCamera default disabled
