A_FaceTracer is an action that immediately changes the actor's angle to be facing its tracer, similarly to
A_FaceTarget. If the actor doesn't have a tracer however, this action will do nothing.

// var2 = unused
void A_FaceTracer(mobj_t *actor)
if (LUA_CallAction("A_FaceTracer", actor))
actor->angle = R_PointToAngle2(actor->x, actor->y, actor->tracer->x, actor->tracer->y);
