Patch kitty for old OpenGL

[sarmong]

I have an old thinkpad x201 and it has OpenGL 2.0. I know that kitty doesn't support it.

However, I don't really want to set up another terminal emulator, so my question is:

How can I patch kitty to be used on older OpenGL versions (obviously at my own risk) and what features will stop working?

No idea, have never even looked at supporting more than decade old versions of OpenGL. kitty uses a few functions introduced in 3.3 as wella s some shader features. Am fairly sure it would be a significant amount of work to try to get it running on OpenGL 2.0
