**Problem**
- whenever you want more than one of the builtin cameras (for example multiple windows, split screen, portals), you need to add a render graph node that executes the correct sub graph, extract the camera into the render world and add the correct `RenderPhase<T>` components
- querying for the 3d camera is annoying because you need to compare the camera's name to e.g. `CameraPlugin::CAMERA_3d`
**Solution**
- Introduce the marker types `Camera3d`, `Camera2d` and `CameraUi`
-> `Query<&mut Transform, With<Camera3d>>` works
- `PerspectiveCameraBundle::new_3d()` and `PerspectiveCameraBundle::<Camera3d>::default()` contain the `Camera3d` marker
- `OrthographicCameraBundle::new_3d()` has `Camera3d`, `OrthographicCameraBundle::new_2d()` has `Camera2d`
- remove `ActiveCameras`, `ExtractedCameraNames`
- run 2d, 3d and ui passes for every camera of their respective marker
-> no custom setup for multiple windows example needed
**Open questions**
- do we need a replacement for `ActiveCameras`? What about a component `ActiveCamera { is_active: bool }` similar to `Visibility`?
