// TODO: automatic cache eviction

/// Installs the default set of loaders:
/// - `file` loader on non-Wasm targets
/// - `http` loader (with the `ehttp` feature)
/// - `image` loader (with the `image` feature)
/// - `svg` loader with the `svg` feature
///
/// ⚠ This will do nothing and you won't see any images unless you enable some features!
/// If you just want to be able to load `file://` and `http://` images, enable the `all-loaders` feature.
///
/// ⚠ The supported set of image formats is configured by adding the [`image`](https://crates.io/crates/image)
/// crate as your direct dependency, and enabling features on it:
///
/// ```toml,ignore
/// image = { version = "0.24", features = ["jpeg", "png"] }
/// ```
///
/// See [`egui::load`] for more information about how loaders work.
