4891          * Edits the input history of cl_movement by rotating all move commands
4892          * currently in the queue using the given transform.
4893          *
4894          * The vector passed is an "angles transform" as used by warpzonelib, i.e.
4895          * v_angle-like (non-inverted) euler angles that perform the rotation
4896          * of the space that is to be done.
4897          *
4898          * This is meant to be used as a fixangle replacement after passing
4899          * through a warpzone/portal: the client is told about the warp transform,
4900          * and calls this function in the same frame as the one on which the
4901          * client's origin got changed by the serverside teleport. Then this code
4902          * transforms the pre-warp input (which matches the empty space behind
4903          * the warp plane) into post-warp input (which matches the target area
4904          * of the warp). Also, at the same time, the client has to use
4905          * R_SetView to adjust VF_CL_VIEWANGLES according to the same transform.
4906          *
4907          * This together allows warpzone motion to be perfectly predicted by
4908          * the client!
4909          *
4910          * Furthermore, for perfect warpzone behaviour, the server side also
4911          * has to detect input the client sent before it received the origin
4912          * update, but after the warp occurred on the server, and has to adjust
4913          * input appropriately.
