different adaptive sampling noise threshold per ray type.

I often find that the adaptive sampler stops too early on reflective and transmissive pixels, forcing me to use a lower noise threshold than necessary for the majority of the image.

Would be awesome if the adaptive sampler could check the noise value of each pass rather than just the combined pass, and consider the pixel still noisy if any of the passes are noisy regardless of the noise level of the combined pass.

The user could also specify a noise threshold offset for each ray type in the viewlayer panel's passes area. This would allow the user to tune the adaptive sampler for a more even noise level from individual passes. Once the per ray offsets are set, the user would only need to modify the current noise threshold in the render panel's sample settings options to quickly specify the overall quality required for each render.
