Combine `intensityDistribution` and `intensity` for lights?

[UX3D-haertl]

One could simplify KHR_LIGHT_QUAD and KHR_LIGHT_RING by combining these two parameters. Just use the intensity parameter which can have type FLOAT32 or ARRAY1D / ARRAY2D of FLOAT32. This would be similar to the color/opacity parameter in volume. Or is there a reason not to do this?

This is an intriguing proposal. One possible disadvantage is that then there is no easy way to uniformly scale the brightness of the light (keeping the intensity distribution), or to combine intensityDistribution with power or radiance.

After discussion in WG we like to keep parameters separate, for the reasons given above.
