* Output to floating point framebuffers so that results are not truncated
to 8 bit normalized values.
* Tighten the epsilon from 1/255 to 0.0005. May need further tweaking as
more GPUs are tested.
* Explicitly check for -inf and inf values when they were previously
rounded to 0 and 255.
* Explicitly check for clamping of overflowed normalized floats by
providing the expectations instead of computing them.
