Make Sampler constructor API more robust #65
Description
We have had multiple feedback that the Sampler constructor API is not clear enough. Specifically the 'frame' argument could be further documented.
Care should be made here to cater to language used in both the offline rendering, and the game communities as there is often nuances in the definition of frame, iteration, and sample index.
We could also experiment, and go one step further, adding dedicated types to the integer arguments to make sure their order isn't accidentally mixed by the calling code.
