Posting notes here to improve the documentation.

  1. Glium's Backend takes &self in all methods
  2. Because of 1) a mutable reference to the window must be created from an immutable one
  3. To solve 2) a Rc<RefCell<W>> is used in the Wrapper struct, which implements Backend
  4. Because of 3) the user is required to wrap the window in Rc<RefCell<W>> at startup

Rc<RefCell<W>> might have some issues with if let and while let expressions. When using GliumWindow::next, this is not a problem.
