6/// server-side counterpart on every compositor it is used with.
7///
8/// The counterpart is reference counted per compositor: each render data
9/// that draws with the object holds a reference until it is disposed.
10/// `get_for_compositor` is the generic `GetForCompositor` of upstream; the
11/// id refers to a server object that exposes the resource's interface
12/// (`IServerObject::as_brush`, `as_pen`, `as_render_data_geometry`).
