Since we landed damage tracking we could try to go even further and make use of EGL_EXT_buffer_age and GLX_EXT_buffer_age. So platforms other than Wayland would get benefits from recent damage tracking addition.

I'm not sure whether macOS/Windows provide something similar, but at least it'll work on X11/Wayland. If someone is aware which extensions to use on macOS/Windows for that let me known.

Also, there's some other API (EGL_KHR_partial_update), but I'm not sure that it's widely adopted and I only saw it with lima driver.

Use buffer age to perform partial rendering
30c4f02 
This commit makes uses of buffer age extension and recent
alacritty_terminal damage tracking to perform partial redraws on
platforms supporting `GLX_EXT_buffer_age` and `EGL_EXT_buffer_age`.

The alacritty_terminal damage tracking was enhanced in a way that it
reports damage only up to `occ`, so partial redraws during scrolling
are possible.

Fixes alacritty#5843.
