<pre>On me Mesa DRI Intel(R) Haswell Mobile I actually get the reverse problem:
$ ./bin/gl-1.4-polygon-offset -auto
Actual MRD is too large (may waste depth-buffer range)
Ideal MRD at near plane is 5.960283e-08 (nominally 1 bit)
Actual MRD at near plane is 1.192093e-07 (nominally 2 bits)
Ideal MRD at infinity is 4.353401e-08 (nominally 1 bit)
Actual MRD at infinity is 1.192093e-07 (nominally 2 bits)
PIGLIT: {"result": "fail" }
So the test itself doesn't seem to be limited to 1 bit as I considered.
Still no idea on how to fix it. I'm reluctant just to bump MRD on llvmpipe, as
I'm afraid it will cause problems with different state trackers.
It's not a huge deal neither.
In short, I'm afraid there's little chance for a fix any time soon..</pre>
