I'm worried that the baby thinks people can't change.

      [1/2] Here is a demo of a simple, completely unoptimized terminal renderer I wrote over a few days. Supports scrollback, line wrapping, Unicode combining, RTL-over-LTR, multicolor fonts, changing fonts on the fly, etc. It runs at several thousand FPS.https://youtu.be/hxM8QmyZXtg

      [2/2] This was in response to the outlandish parade of excuses that I heard when I stated that it was simple to make a terminal render at several thousand frames a second, even with Unicode and color support. Hopefully this rains as thoroughly as possible on that insane parade.

      (And as I say in the video, I would actually consider this code to still be _quite slow_. I did not profile or optimize the code at all. An optimized version of this code could perform significantly faster on a number of important metrics, specifically ingress speed)

      First, thanks for doing this, maybe somebody at MS can learn from this. Second, any chance this is going to be open-sourced, made available to the terminal guys at MS so every Windows user can profit from your work? (I understand why you would be reluctant though).

      It's on GitHub, GPLv2. Any GPLv2 compliant codebase can use it - but really there isn't even any reason to? It's literally just an LRU cache in front of the glyph generator (DirectWrite). That's all you need to do. Anyone can type one in over a few hours!

          I presume this is how most video games have worked for a long time, except for a few modern ones that rasterize on the GPU (it is what Braid and The Witness did).

          Oh and then there's Earth Defense Force 4.1, which actually used Windows font rendering for some reason, so that if you went and changed your desktop font scale, it would mess up all the formatting in the game, "Yay"...
