Ancient X11 scaling technology

Brilliant. This is another piece of evidence on the pile of why we got Wayland: it's because people who understood X11 mostly retired and everyone else couldn't be bothered to learn X11 because it's "yucky C code" or something. And it bothers me that we lose remote rendering with Wayland (unless one fights with waypipe) that was just built-in to X11. Yes, it was slow, but actually if you're running a VM on your local system and using SSH to connect to it, then it works great. Sigh. I'm an old person yelling at clouds.

> Yes, it was slow,

Not particularly if you are on a low latency network. Modern UI toolkits make applications way less responsive that classical X11 applications running across gigabit ethernet.

And even on a fast network the wayland alternative of 'use RDP' is almost unusable.

the approach used in this blog post requires rdp. It's not drawing using X, so there's no vector network transparency.

Nope, this post is using GLX over the network.
