* Resource intensive - use sparsely
* `set_lighting(light_definition)`: sets lighting for the player
* Passing no arguments resets lighting to its default values.
* `light_definition` is a table with the following optional fields:
* `saturation` sets the saturation (vividness).
* `saturation` sets the saturation (vividness; default: `1.0`).
values > 1 increase the saturation
values in [0,1) decrease the saturation
* This value has no effect on clients who have the "Tone Mapping" shader disabled.

* `exposure` is a table that controls automatic exposure.
The basic exposure factor equation is `e = 2^exposure_correction / clamp(luminance, 2^luminance_min, 2^luminance_max)`
* `luminance_min` set the lower luminance boundary to use in the calculation
* `luminance_max` set the upper luminance boundary to use in the calculation
* `exposure_correction` correct observed exposure by the given EV value
* `speed_dark_bright` set the speed of adapting to bright light
* `speed_bright_dark` set the speed of adapting to dark scene
* `center_weight_power` set the power factor for center-weighted luminance measurement
* `luminance_min` set the lower luminance boundary to use in the calculation (default: `-3.0`)
* `luminance_max` set the upper luminance boundary to use in the calculation (default: `-3.0`)
* `exposure_correction` correct observed exposure by the given EV value (default: `0.0`)
* `speed_dark_bright` set the speed of adapting to bright light (default: `1000.0`)
* `speed_bright_dark` set the speed of adapting to dark scene (default: `1000.0`)
* `center_weight_power` set the power factor for center-weighted luminance measurement (default: `1.0`)
* `get_lighting()`: returns the current state of lighting for the player.
* Result is a table with the same fields as `light_definition` in `set_lighting`.
