Okay, I think I get what you mean.

What if the picture has been rotated? I agree an extra translation has
to occur at the filter level to correct this filtering effect. 

So yes, there is a vout design issue here.

But, that should not prevent from correcting a bug that has nothing to
do with this design issue.

Whatever the formula (and it can be challenged), let's make sure the
resulting range of value is not truncated in an unfortunate way (nothing
to do with a rationale, just a developer forgetting to update those
boundary tests). At least, code will be more understandable and a bug is
