Struct CompositionCustomVisualHandler 

pub struct CompositionCustomVisualHandler { /* private fields */ }

The state upstream’s abstract CompositionCustomVisualHandler keeps, and its protected members: what a handler class embeds and returns from ICompositionCustomVisualHandler::handler_base.

The handler is created on the UI thread and used on the server only: it is attached to the server-side custom visual when that visual is created.
