Ian Douglas Scott 129069996e Split GraphicsContext into Context and Surface ... A `Context` is created with a display handle, and a `Surface` is created with a `&Context` and a window handle. Thus multiple windows can be created from the same context without duplicating anything that can be shared. This API is broadly similar to `wgpu` or `glutin`. On Wayland, the `Context` contains the `EventQueue`, which is shared between windows, and the `WlShm` global. On X11, `Context::new` checks for the availability of XShm, and contains a bool representing that as well as the `XCBConnection`. The shared context data is stored within the window in an `Arc`. On other platforms, the display isn't used and `Context` is empty. This does however test that the display handle has the right type on those platforms and fail otherwise. Previously the code didn't test that. Closes https://github.com/rust-windowing/softbuffer/issues/37.		2023-01-06 21:36:53 -08:00
