Kirill Bulatov 6110aa61e1 Improve icon handling on startup (#65173)
## First commit

Preload initial project panel icons before drawing
Preload the initial project panel icons through the asset cache.

Measurements (warm macOS launches):

- Time to complete Catppuccin Frappe icons: reductions of 4.0 ms and
16.2 ms in two runs of 10 pairs.
- Time to first nonblack captured frame: increases of 16.6 ms and 2.3
ms; all 16 icons were present in every candidate launch.

## Second commit

Reuse unchanged icon families during startup instead of loading them
twice.
Reuse icon families with unchanged source bytes and paths until
extensions finish loading.
Include file paths in theme-read errors.

Measurements (warm macOS launches):

- Time to first captured complete Catppuccin Frappe icons: paired median
reductions of 6.2 ms and 5.0 ms in two runs of 10 pairs.
- Capture gaps in the repeat run reached 216.7 ms.


Release Notes:

- Improved startup time when custom icons are used

Licensing

Zed source code is licensed primarily under GPL-3.0-or-later, with Apache-2.0 components where marked.

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.
