Remove the dependency on installShellFiles as it is not needed for building kitty itself and is only used in Nixpkgs for conveniently installing man pages and shell completions.
pkgconfig has been renamed to pkg-config.
Use `with python3Packages;` to reduce code duplication. This is how it's done in Nixpkgs as well.
Also sort the packages in nativeBuildInputs.
Apparently nvim assumes cnorm doesn't affect cursor shape. It's
ambiguous whether cnorm should affect it or not. So to prevent
regressions in case other programs assume that as well, have it only
make the cursor visible and blinking, without changing its shape.
Right now visual bell makes background flash sharply with bright white
(when configured with darkish color theme). This causes eye strain,
especially prominent in unlit environments.
This change makes background bounce smoothly between regular bg color
and highlight (selection) bg color for the configured visual bell
duration. Intensity is animated with cubic easing functions. It
currently peaks at 20% of the duration, this is hardcoded.
Mark functions computing intensity and easing as inline
Do smarter blending of visual bell flash
Blend highlight color with pegtop's softlight mode over both background
and half as much over foreground. This should help with flash visibility
in light themed and inverted colors contexts.
Blend flash in BACKGROUND pass also
