Camera serialization fails due to unregistered types.

[kidrigger]

Bevy version

0.12.1

What you did

1. Use the scene serialization example.
2. Add a default Camera3dBundle to a scene before serialization.
3. Run program without input file.
4. Rename generated load_scene_example-new.scn.ron to load_scene_example.scn.ron to use as input.
5. Re-run program to use the file as input.
6. Error

What went wrong

Deserialization fails with:

bevy_asset::server: Failed to load asset 'scenes/load_scene_example.scn.ron' with asset loader 'bevy_scene::scene_loader::SceneLoader': Could not parse RON: 100:31: no registration found for type bevy_core_pipeline::core_3d::camera_3d::Camera3dDepthTextureUsage

Relevant Serialized RON

 "bevy_core_pipeline::core_3d::camera_3d::Camera3d": (
          clear_color: Default,
          depth_load_op: Clear(0.0),
          depth_texture_usages: (16),
          screen_space_specular_transmission_steps: 1,
          screen_space_specular_transmission_quality: Medium,
        ),

If it's not clear, break this out into:

• What were you expecting?
  Serialized file can be deserialized.
• What actually happened?
  Types used by Camera3D are not registered and cannot be loaded.
  Note:

Additional information

Changes to the example:

Add to line 118 in the scene sample

scene_world.spawn((Camera3dBundle::default(), Name::from("TestThis")));
