don’t know why the current softpipe/swrast implementation shouldn’t be

Interesting I hadn't known we had a correct impl in mesa, the features.txt has said
"softpipe and llvmpipe advertise 16x anisotropy but simply ignore the setting"
so I never dug any deeper. I'll consider a port of this to llvmpipe at some
point, making it efficient might be tricky.
It seems that features.txt hasn't been updated regarding this functionality; softpipe has
"real" anisotropy since 2011.

That would be great. As anisotropic filtering is often an option which can be
set by a user, I guess most people turn it off to get higher framerates. But in
our use case, high quality renderings are required, so we accept the longer
render times to get the best quality; hopefully a llvmpipe port would be faster
than the old swrast implementation (we are only using the fixed rendering
pipeline/no shaders in conjunction with the OpenMP patch for speeding up
GL_POLYGON_SMOOTH_HINT)

Is my first pass at writing the code for this I've no idea if this is
anyway correct, but I'm just letting everyone know I've started
working on it, and mipmap_tunnel doesn't look immediately wrong.
Olay the code in the MR above seems to work in most cases now and
seems to operate like softpipe.
However I'm seeing a trace failure

The floor at the bottom left of the Actual image definitely looks odd,
there's a hard line between the rock patterns.
