//- finish player physics code (cs_runplayerphysics)
//- EntWasFreed ?
//- RF_DEPTHHACK is not like it should be
//- add builtin that sets cl.viewangles instead of reading "input_angles" global
//- finish lines support for R_Polygon***
//- insert selecttraceline into traceline somehow

//4 feature darkplaces csqc: add builtin to clientside qc for reading triangles of model meshes (useful to orient a ui along a triangle of a model mesh)
//4 feature darkplaces csqc: add builtins to clientside qc for gl calls

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