So what does the test expect? I'm kind of curious what the result should be,
since I'd be a bit surprised if the missing texel ought to really be
interpolated with the other 3 texel colors. Yes gl spec suggests this but I
don't think this is really meant for integer textures.
In any case gl doesn't actually mandate anything specific for this texel, even
with ordinary filtering.
