4886          * The vector passed is an "angles transform" as used by warpzonelib, i.e.
4887          * v_angle-like (non-inverted) euler angles that perform the rotation
4888          * of the space that is to be done.
4889          *
4890          * This is meant to be used as a fixangle replacement after passing
4891          * through a warpzone/portal: the client is told about the warp transform,
4892          * and calls this function in the same frame as the one on which the
4893          * client's origin got changed by the serverside teleport. Then this code
4894          * transforms the pre-warp input (which matches the empty space behind
4895          * the warp plane) into post-warp input (which matches the target area
4896          * of the warp). Also, at the same time, the client has to use
4897          * R_SetView to adjust VF_CL_VIEWANGLES according to the same transform.
4898          *
4899          * This together allows warpzone motion to be perfectly predicted by
4900          * the client!
4901          *
4902          * Furthermore, for perfect warpzone behaviour, the server side also
4903          * has to detect input the client sent before it received the origin
4904          * update, but after the warp occurred on the server, and has to adjust
4905          * input appropriately.
