Thorsten Ball e69f9d6cf9 linux/x11: Fix gap when tiling windows side by side (#13859)
By leveraging the `_GTK_EDGE_CONSTRAINTS` atom we can get all four
booleans for the `Tiling` struct and figure out which side is free when
the window is tiled to half of the screen.

For the logic behind the `_GTK_EDGE_CONSTRAINTS` see:
-
https://github.com/GNOME/mutter/blob/8e9d13aa3b3baa099ca32bbcb10afb4d9eea4460/src/x11/window-x11.c#L65-L75

(I used Claude 3.5 Sonnet with our code and these pieces from `mutter`
to generate the Rust code, that was pretty sweet)

This fixes the gap in the middle when a GPUI window is tiled to the left
and another window to the right.

It's not _perfect_ but it looks a lot better.

Here's a diff that makes it look better:

                         let size = cx.window_bounds().get_bounds().size;
```

But that makes it look weird on Wayland, so I didn't do it.

I think it's fine for now. Chromium looks bad and has a gap, so we're
already better.

Zed

CI

Welcome to Zed, a high-performance, multiplayer code editor from the creators of Atom and Tree-sitter.

Installation

You can download Zed today for macOS (v10.15+).

Support for additional platforms is on our roadmap:

For macOS users, you can also install Zed using Homebrew:

brew install --cask zed

Alternatively, to install the Preview release:

Developing Zed

Contributing

See CONTRIBUTING.md for ways you can contribute to Zed.

Also... we're hiring! Check out our jobs page for open roles.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
