This code was sent in by Chev. Note that it does not necessarily return the *same* Euler angles as those set by setRotationDegrees(), but the rotation will be equivalent, i.e. will have the same result when used to rotate a vector or node.

The best that we could do would be to arbitrarily make one scale negative if one or three of them were negative. FIXME - return the original values.
