Error Behaviour

The campfire heats you based on how far away your face is from it, instead of your overall body. This means if you place it on a block so that it's raised off of the floor, it gives you more heat.
Secondly, the northwest corner of the campfire is much hotter than the rest, as if it thinks that's the center of the fire.

Expected Behaviour

I would expect the campfire to give the same or less heat when raised on a pedestal, and it should not favor any specific direction.

Reproduce

1. place campfire, raised one block off the ground
2. light it
3. walk around to the northwest of it for the second issue (you will probably take damage from hyperthermia)
