ENH: Lights properties can change at runtime, attenuation added
As the commit message says.
- Light properties changeable at runtime. So you can move a light, etc.
- Attenuation added (VTK exposes constant, linear, or quadratic falloff through 3 coefficients you may set)
- Light used in CameraController example. Press d to detach and see the light move around separately.
