Rotates picked items in the scene around a pivot point.
Rotate objects by incrementing their Euler rotation angles.
This means that the rotation is done first to Z, then Y, then X. Consequently, the X rotational axis depends on the Y and Z rotations already done.
Rotations done on DAG nodes above the current node also affect the rotational axis.
Rotate each picked object around its local X, Y, and Z axes (displayed at each object’s pivot point).
Rotate objects around the world X, Y, and Z axes.
