4043          * of the space that is to be done.
4044          *
4045          * This is meant to be used as a fixangle replacement after passing
4046          * through a warpzone/portal: the client is told about the warp transform,
4047          * and calls this function in the same frame as the one on which the
4048          * client's origin got changed by the serverside teleport. Then this code
4049          * transforms the pre-warp input (which matches the empty space behind
4050          * the warp plane) into post-warp input (which matches the target area
4051          * of the warp). Also, at the same time, the client has to use
4052          * R_SetView to adjust VF_CL_VIEWANGLES according to the same transform.
4053          *
4054          * This together allows warpzone motion to be perfectly predicted by
4055          * the client!
4056          *
4057          * Furthermore, for perfect warpzone behaviour, the server side also
4058          * has to detect input the client sent before it received the origin
4059          * update, but after the warp occurred on the server, and has to adjust
4060          * input appropriately.
