Slider for a light's area of effect range

A way to increase/decrease the area which a light source illuminates without changing its intensity.

As it is now, increasing the intensity also increases the area but also creates a lot of hard shadows which aren't always desirable. I hope adding this option would allow for a more gentle light which extends further and makes illuminating dark maps easier without drowning them in lights.

Additionally, in D&D 5e light sources such as torches create a 40-foot-diameter area of bright light and a further 40 feet of dim light. This is unrealistic for a torch, but I would like to be able to simulate it regardless.
