X.Org Server Git lands support for hardware-accelerated XWayland with NVIDIA

The NVIDIA-led work to allow XWayland OpenGL and Vulkan acceleration with their proprietary driver has just been merged into X.Org Server Git.

The XWayland changes needed to allow the NVIDIA proprietary driver to work in an accelerated manner have landed in X.Org Server 1.21 Git. The main change is xwayland: implement pixmap_from_buffers for the eglstream backend that was merged just a few minutes ago.

NVIDIA is a big blocker for Wayland, so any steps forward are good steps - even if it takes a while before this code ends up on our desktops.
