* Replace `std::mem::uninitialized` with `MaybeUninit`
* Avoid undefined behavior when using `MaybeUninit`
* Restore unused `PointerState` fields as internally public
* Zero-initialize some struct values in Xlib FFI calls
* Reform usage of `MaybeUninit` in Xlib FFI
* Prefer safe zero-initialization using `Default`, when possible
* Zero-initialize integers and floats using `0` or `0.0`
* Use `MaybeUninit::uninit` for large byte buffers and union types
* Use `MaybeUninit::uninit` when the resulting value is ignored
* Fix old `use` declarations
* Fix hidden lifetime parameter
* Fix missing methods in `web::Monitor`.
Originally fixed by @ryanisaacg in 94387c4bf5bca35f4e24562ce89a4f4badd53aa8.
* Disable some tests and examples on `wasm32`
* Fix issues with redraw_requested when called during EventsCleared
* Format
* Fix event dispatch after RedrawRequested but before EventsCleared
This could happen if the event queue was cleared, we processed WM_PAINT,
but the event queue got re-filled before we checked to see it was empty.
* Fix paint ordering issues when resizing window
* Format
* Make FileDropHandler::iterate_filenames more robust
by replacing the call to mem::uninitialized with mem::zeroed and change
file name retrieval to use buffers of exact length as reported
by DragQueryFileW instead of relying on MAX_PATH.
* Change remaining calls of uninitialized to zeroed
* Run rustfmt
* Add CHANGELOG entry and comment
Internally, `XFlush` calls `_XSend` to write data. It then calls
`XEventsQueued(display, QueuedAfterReading)`, which reads data from the
X server connection. This prevents the event loop source callback from
being run, as there is no longer data waiting on the socket.
Ideally, we would want to call `_XSend` directly to ensure that no
output is buffered by Xlib. However, this function is not exported as
part of Xlib's public API.
Testing with the `XFlush` call removed does not appear to adversely
affect the performance of an application. If any bugs should eventually
arise from this change, perhaps another function may be used in place of
`XFlush`, such as `XPending`, which writes buffered output but does not
so aggressively read from the X server connection.
Closes#865
