This PR considers the following constraints: - Resources must be available when building servo via a published crates.io package (i.e. no `../../../resources/<file>` file references). - Minimal setup when writing tests (`nextest` spawns each test in its own process, so we don't want to explicitly initialize the resource handler for every `#[test]` fn) - Use local resources when developing locally - Support loading the resources from a proper resource directory if the embedder wishes so, including via a custom mechanism, not necessarily as files (File) Resources that are only accessed from servoshell are out of scope of this PR, since it mainly focusses on unblocking publishing `libservo` to crates.io. Baking the resources into the binary by default simplifies the setup a lot. We already supported that before, but only for testing purposes and explicitly not for production builds. Using [`inventory`](https://crates.io/crates/inventory) adds a simple way for the embedder to replace the default baked in resources, while also keeping the test usage of baked in resources simple. rippy.png is also referenced from image_cache - We simply duplicate it, since the image is small, to avoid adding unnecessarily complex solutions like adding a dedicated crate. Testing: Covered by existing tests.
