Both of these are already implemented. They are reflection_blur_max and 
reflection_blur_max_adc, in global_settings. My transparency patch has 
similar controls.

I have been thinking about this, something like a depth_blur_scale or 
something. I don't think it would be terribly useful, though, and 
setting the max blur level to 2 or 3 is usually enough.
