[Mesa-dev] [PATCH 0/9] Implement textureQueryLod in softpipe

[Krzesimir Nowak]

The following patches do some preparatory refactoring in softpipe's
sp_tex_sample.{c,h} before actually implementing the feature.

There is also a patch that fixes softpipe's textureLod with bias. I
caught this bug when finished the textureQueryLod implementation - one
of four textureQueryLod tests were failing because of it. I sent
patches adding the testcases with non-zero lod-bias value to piglit
mailing list
(http://lists.freedesktop.org/archives/piglit/2015-September/017018.html).

Also, this is my first contribution to mesa, but I hope I didn't make
any obvious mistakes.

Thanks.
