/**
* Teleports the passed in Entity through the portal.
*
* <p>Given an Entity object, attempts to teleport them through the portal. This involves many
* steps. 1) Verify the portal on the other end still exists. If it doesn't, mark this as such. 2)
* If there is no counterpart, figure out where it would be, and get it. This may involve
* generating and placing a portal into the world. 3) Assuming we now have a counterpart, figure
* out where to teleport the entity to. 3a) Figure out the entity's position relative to the entry
* portal. 3b) Translate this to a position relative to the exit portal. 3c) Preserve the entity's
* camera's orientation relative to the portal. 4) Teleport the entity. 4a) If the entity is a
* Player in a vehicle, we do a dance. - Raise the destination by 1 (vehicles have to 'fall' into
* the portal to avoid losing momentum, so they should be one higher). - Make the player leave the
* vehicle. - Spawn a new minecart at the destination. - Teleport the player to the destination. -
* Make the player a passenger of the minecart. - Give the new minecart the (properly translated)
* velocity of the old vehicle. - Remove the old vehicle.
*
* @param e The entity to teleport.
* @return The location the entity was teleported to, or null if the entity was not teleported.
