This is great! Would've been really useful a couple months ago when I was refactoring Lavapipe's texture filtering. I worked off the Vulkan spec, which doesn't mention the elliptical transformation. I did notice that the spec says:

> The minimum and maximum scale factors (ρmin, ρmax) should be the minor and major axes of this ellipse.

Where "should" probably means some transformation can be applied (would be "must" otherwise).

Now I'm tempted to implement your visualizations so I can compare my work to your hardware references, and spend more hours getting it closer to actual hardware.
