[Mesa-dev] GL_ARB_texture_query_lod

[Dave Airlie]

In case anyone is interested I've implemented the GLSL and some
gallium bits in a branch in my repo.

I'm not really sure there is much point in pushing forward with this
until we are bit closer to GLSL 4.00.

The main problem is the spec uses the shader function textureQueryLOD,
and GLSL 4.00 uses textureQueryLod
and I doubt apps if they use this will bother with the pre-GLSL 4.00 version.

I've written some piglit compiler level tests for both interfaces,
that I'll send in at some point, but I haven't gotten
to execution tests.

Dave.
