The 12-element array is a 3x3 matrix (with a fake 4th column for
padding) describing the rotation.  Extracting the rotation
information from this into another form is not *entirely* trivial
(but see the matrices and quaternions faq all over the internet),
but it may be 'used' directly to rotate vectors through matrix
multiplication, or fed almost straight to OpenGL for use as a
modelview.
