waffle f738fbd4f8 gpui: Disable rounding in the layout engine (#31836)
Rounding broke (among other things, probably) pixel-perfect image
rendering with non-power-of-two scaling factor.

An example which reproduces the problem can be found
[here](https://github.com/WaffleLapkin/gpui_taffy_rounding_whyyyyy).

How it looks with `gpui` from `main`:

How it looks with this patch:

Both screenshots are made on kde+wayland with magnification using kde's
built-in magnification (`Meta`+`+`, `Meta`+`-`). Note that screenshot
apps have a high chance of lying 🙃

The image itself is 400 by 300 pixels of red/green checkerboard pattern
made specifically to exaggerate scaling issues.

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.
