	The rotation vector is in degrees. They rotate in the order of
appearance, first X then Y then Z. You can have multiple vectors
if you want to rotate them in a different order such as <0,Y,0>
<0,0,Z> <X,0,0> That will rotate in Y Z X order.

	That is a one degree rotation around Y that you most likely can
not see on the rendering.

	Since a box is 90 degree symetric, play with 30 and 45 degrees
to see the results.
