This looks ok to me (I put in the comment about this not making sense in
the first place...).
It should be noted though and I'd have preferred if a comment would
still say that somewhere that even with this the behavior isn't quite
right neither (though arguably much better) and the reason I didn't
actually fix it at that time since it was a bit more complex, what will
happen is that we'll do bilinear filter first, then replace with 0/1
depending on the filtered result. GL actually allows this but ideally
you'd really exchange the values with 0/1 _before_ doing the bilinear
filter.
