Sergei G. f9d57b54dc component_preview: Fix example rendering no text or icons (#59241)
`cargo run -p component_preview --example component_preview` does not
work.
On current main it panics at startup:

```
thread 'main' panicked at crates/gpui/src/action.rs:296:13:
Action with name `zed::Quit` already registered
```

With that panic fixed, the window opens but renders no text and no icons
(see Showcase below).s

## Solution

Root cause for the blank window: `component_preview` package resolves
`gpui_platform` with just `"screen-capture"`.

On macOS the missing `font-kit` feature makes `MacPlatform` fall back to
`gpui::NoopTextSystem`, as mentiond also in README (or CONTRIBUTE) file.

On Linux the missing `wayland`/`x11` features leave no windowing backend
at all.

list of changes:

- Enable the same `gpui_platform` features as the `zed` binary.
- Attach `Assets` and load the embedded fonts.
- Initialize `env_logger` so platform warnings reach the terminal.
- Fix three startup panics: move the example's `Quit` action to the
`component_preview` namespace.

## Testing

Tested on macOS/Linux, not tested on Windows. I use Parallel VMs.

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.
