void ~GraphicalPresenter ()void PresentView (::fuchsia::element::ViewSpec view_spec, ::fidl::InterfaceHandle< ::fuchsia::element::AnnotationController> annotation_controller, ::fidl::InterfaceRequest< ::fuchsia::element::ViewController> view_controller_request, PresentViewCallback callback)Presents the view described by `view_spec`.
If `view_controller_request` is provided, it will be connected to a `ViewController`
implemented by the `GraphicalPresenter` server. When the view is dismissed,
the `ViewController` channel is closed with a `ZX_OK`, at which point it is safe
to clean up resources backing the view. To dismiss the view, the client should
call `ViewController.Dismiss()` and wait for the `ZX_OK` epitaph.
Not providing a `view_controller_request` handle will make it impossible for the
client to observe the view's lifecycle.
+ `view_spec` describes the view to present
+ `annotation_controller` a handle to an `AnnotationController`, allowing the
`GraphicalPresenter` server to observe and update the view's annotations.
+ `view_controller_request` an optional request for a controller for the view
* error `view_spec` must contain `view_holder_token` and `view_ref` for Gfx views,
OR `viewport_creation_token` for Flatland views, but never both. If both are
set, error `PresentViewError.INVALID_ARGS` is returned.
* error `PresentViewError.INVALID_ARGS` if `spec.view_holder_token` or
`spec.view_ref` are missing or invalid.
