Editor viewport vs window

The editor window's render canvas is owned by the GUI, and is thus not accessible. Attempting to create a render canvas for this window will result in an InvalidOperationException.

Instead, the enabled viewport is the existing ViewportRenderInstance provided in the entry and exit. This cannot be disposed as it is owned by the editor.

Additional viewports

The editor may display multiple viewports, and they can be queried in the Viewports field. Once a viewport is closed, it is automatically destroyed and cannot be accessed anymore. It is important to NOT rely on them being alive for the duration of the editor.
