Mesa provides OpenGL/Vulkan drivers for Intel/AMD cards and also VAAPI/VDPAU
drivers for AMD cards. Recently, a new minor version was released. So far it
was only tested via drm-stable-kmod on 12.0-CURRENT. Can someone test on
FreeBSD < 11.2 for regressions? If you find any don't forget to attech
/var/log/Xorg.0.log and LIBGL_DEBUG=verbose output.

I'd like to land the update in 2 weeks.
