--- Comment #2 from Roland Scheidegger <sroland at vmware.com> ---
I forgot to mention, I have no idea what the fourth texel should be in case of
cube corners for integer textures. As said I highly doubt averaging is the
answer, but apart from that no idea. Hopefully though a randomly selected texel
from the other 3 is good enough...
I don't think this is mentioned anywhere in the spec (and for d3d it doesn't
really apply since integer textures are supposed to only be fetched,
sample/gather is not really legal although might work).
