I can't underrate anisotropic filtering.
# Objective
- Allow easily enabling anisotropic filtering on glTF assets.
- Allow selecting `ImageFilterMode` for glTF assets at runtime.
## Solution
- Added a Resource `DefaultGltfImageSampler`: it stores
`Arc<Mutex<ImageSamplerDescriptor>>` and the same `Arc` is stored in
`GltfLoader`. The default is independent from provided to `ImagePlugin`
and is set in the same way but with `GltfPlugin`. It can then be
modified at runtime with `DefaultGltfImageSampler::set`.
- Added two fields to `GltfLoaderSettings`: `default_sampler:
Option<ImageSamplerDescriptor>` to override aforementioned global
default descriptor and `override_sampler: bool` to ignore glTF sampler
data.
## Showcase
Enabling anisotropic filtering as easy as:
```rust
app.add_plugins(DefaultPlugins.set(GltfPlugin{
default_sampler: ImageSamplerDescriptor {
min_filter: ImageFilterMode::Linear,
mag_filter: ImageFilterMode::Linear,
mipmap_filter: ImageFilterMode::Linear,
anisotropy_clamp: 16,
..default()
},
..default()
}))
```
Use code below to ignore both the global default sampler and glTF data,
having `your_shiny_sampler` used directly for all textures instead:
```rust
commands.spawn(SceneRoot(asset_server.load_with_settings(
GltfAssetLabel::Scene(0).from_asset("models/test-scene.gltf"),
|settings: &mut GltfLoaderSettings| {
settings.default_sampler = Some(your_shiny_sampler);
settings.override_sampler = true;
}
)));
```
Remove either setting to get different result! They don't come in pair!

## Migration Guide
- The new fields in `GltfLoaderSettings` have their default values
replicate previous behavior.
