Mesa 26.1.0 released bringing lots of Linux graphics driver enhancements

Mesa 26.1.0 is out now as the latest new-feature release of open source graphics drivers for Linux, with upgraded Vulkan support and performance improvements.

The official news post is not out yet, but the mailing list announcement went out last night. Noted in the announcement:

- VirGL is no longer considered maintained any more. Unless someone steps up to maintain it in the long run, the code is likely to start bit-rotting and might eventually be removed. We recommend users start moving over to other solutions sooner rather than later.
- Intel i915 Iris, Crocus and ANV (excluding HASVK) drivers got VirtIO-GPU native-context driver support for a thinner/faster Intel GPU paravirtualization in a VM.
- OpenGL ES 2.0 is now supported on PowerVR GPUs via Zink.
- Static C++ stdlib is now required on rusticl to workaround applications using their own C++ stdlib.
