* `fov`: FOV value.
* `is_multiplier`: Set to `true` if the FOV value is a multiplier.
Defaults to `false`.
* Set to 0 to clear FOV override.
* `get_fov()`:
* Returns player's FOV override in degrees, and a boolean depending on whether
the value is a multiplier.
* Returns 0 as first value if player's FOV hasn't been overridden.
* `set_attribute(attribute, value)`: DEPRECATED, use get_meta() instead
* Sets an extra attribute with value on player.
