Creates a point light that can be added to a 3D scene.
A point light has a specific location (unlike ambient light) and shines in all directions (unlike a spotlight).
For objects having shaders that respond to lighting, causes parts of the object that face the light to be brighter than parts that face away from the light.
Range— The distance (in Vuo Coordinates) the light reaches. For example, a value of 1 means that objects within a radius of 1 unit of the light will be lit.
Sharpness— How sharp the edge of the light is. A value of 0 means the transition from light to dark is very gradual; a value of 1 means the transition is immediate.
