/// Wrapper for objects which winit will access on the main thread so they are effectively `Send`

/// # Safety
///
/// Winit can run only one event loop at a time, and the event loop itself is tied to some thread.
/// The objects could be sent across the threads, but once passed to winit, they execute on the
/// main thread if the platform demands it. Thus, marking such objects as `Send + Sync` is safe.
