@nprofile1q... @nprofile1q... Ah, ok, that is what you mean. I'm still not quite sure why you would do that though. Maybe I don't understand exactly what you mean, but that sounds like a way of breaking floating point precision. If you map 0->1 to 1->0 that breaks the extra floating point accuracy near zero, which is crucial to the no-clip-plane thing we just discussed.
