dnkl/foot 1.22.0 on Codeberg

Support for toplevel edge constraints. When the compositor indicates the toplevel has edge constraints, foot will not allow the window to be resized (via CSDs) in the constrained directions.
Virtual modifiers (e.g. Alt instead of Mod1, Super instead of Mod4 etc) in key bindings are now recognized as being virtual, and are automatically mapped to the corresponding real modifier. This means you can use e.g. Alt+b instead of Mod1+b.
alpha-mode option to foot.ini. Defaults to default. This config changes how alpha is handled on background colours not set by the terminal.(e.g. vim) (#2026)

UTF-8 error recovery now discards fewer bytes.
Auto-calculated dimmed and brightened colors (e.g. when custom dim colors has not configured) is now done by linear RGB interpolation, rather than converting to HSL and adjusting the luminance (#2006).
Virtual modifiers in keyboard events from the compositor are now supported. This works around various issues seen when running foot under mutter (GNOME) (#2009):
- Some key combinations generating the wrong escape sequence in the kitty keyboard protocol.
- some of foot's default shortcuts not working (mainly those using Mod1) out of the box.
Default URL regex changed to a much more strict variant (#2016). You can manually set the old one, if you prefer it over the new regex.
A tiled window can now be resized in the corners (via CSDs), unless the compositor has indicated the toplevel has edge constraints.

Regression: assertion in url-mode.c when activating a second URL via show-urls-persistent (#2000).
Build failure (srgb.h not found) when doing a parallel build.
Regression: reflowing (changing the window size) removing empty lines (#2011).
url/regex-copy not handling double-width characters correctly (#2027).
