+         * And with the results in SL.
+         *
+         * It's also possible to calculate llEuler2Rot by direct multiplication of

-        a vector pointing along the X axis, first rotating it 3 degrees around the global Z axis, then rotating the resulting

-         *
-         * Experiment in SL to determine conventions:

-         *   llEuler2Rot(<0,PI,0>)=<0,1,0,0>
-         *   llEuler2Rot(<0,0,PI>)=<0,0,1,0>
-         *
-         * Important facts about Quaternions
-         *  - multiplication is non-commutative (a*b != b*a)
-         *  - http://en.wikipedia.org/wiki/Quaternion#Basis_multiplication
-         *
-         * Above SL experiment gives (c1,c2,c3,s1,s2,s3 as defined in our llEuler2Rot):
-         *   Qx = c1+i*s1
-         *   Qy = c2+j*s2;
-         *   Qz = c3+k*s3;
