Description

With the new 0.30 winit ApplicationHandler API using a Pixels<'a> for any lifetime other than 'static just got significantly harder, because all app state must now exist within one struct, which must exist before opening the window. The current workaround is to store an Arc<Window> and create the Pixels<'static> from it; but it would be far easier if the Pixels could own the window and simply have an accessor through which application code can use its own Window. Otherwise a self-referencing struct would be required with the Pixels referencing the Window stored alongside it in the same struct.

Anyways I'm proposing Pixels::window(&self) + Pixels::window_mut(&mut self) that return a reference to the winit::window::Window the Pixels was created with

Contributor guide

Research direction
Examine the Pixels struct to see how it stores the window, then add public accessor methods `window(&self)` and `window mut(&mut self)` that return references to the winit::window::Window.
