Specification
The Euler angle vector (in radians) is converted to a rotation by doing the rotations around the 3 axes in Z, Y, X order. So llEuler2Rot(<1.0, 2.0, 3.0> * DEG_TO_RAD) generates a rotation by first rotating 3 degrees around the global Z axis, then rotating the result around the global Y axis, and finally rotating that 1 degree around the global X axis.
