* Simplified code a lot, bias based on normalized cascade size. * Lets scale cascades, max distance, etc. without creating acne. * Fixed normal biasing in directional shadows. I removed normal biasing in both omni and spot shadows, since the technique can't be easily implemented there. Will need to be replaced by something else.

A Spotlight is a type of [Light3D] node that emits lights in a specific direction, in the shape of a cone. The light is attenuated through the distance. This attenuation can be configured by changing the energy, radius and attenuation parameters of [Light3D].

The maximal range that can be reached by the spotlight. Note that the effectively lit area may appear to be smaller depending on the [member spot_attenuation] in use. No matter the [member spot_attenuation] in use, the light will never reach anything outside this range.
