Nathan Sobo d3c1966d96 WIP: Return WindowHandle<V: View> from AppContext::add_window (#2820) ... Instead of returning a usize for the window id, I'm instead returning a `WindowHandle<V: View>` where `V` is the type of the window's root view. @as-cii helped me with a cool technique using generic associated types where methods on `WindowHandle` can return either T or Option<T> depending on the `BorrowWindowContext::Result` associated type. Some example usage... ```rs let window = cx.add_window(|cx| MyView::new(cx)); let my_view = window.root(cx); // If cx is TestAppContext, returns MyView. Otherwise returns Option<MyView>, because the window could be closed. ``` This isn't insanely beneficial on its own, but I think it will help clean up our testing story. I'm planning on making `window` more useful in tests for laying out elements, etc. - [x] Rework tests that call `add_window` 😅 to expect only a window in return. - [x] Get tests passing - [x] 🚬 test		2023-08-03 18:45:51 -06:00
