Called as part of QWindow::create(), after constructing the window.
Platforms should prefer to do initialization here instead of in the constructor, as the platform window object will be fully constructed, and associated to the corresponding QWindow, allowing synchronous event delivery.

This function is called by Qt whenever a window is moved or resized using the QWindow API.
Unless you also override QPlatformWindow::geometry(), you need to call the baseclass implementation of this function in any override of QPlatformWindow::setGeometry(), as QWindow::geometry() is expected to report back the set geometry until a confirmation (or rejection) of the new geometry comes back from the window manager and is reported via QWindowSystemInterface::handleGeometryChange().
Window move/resizes can also be triggered spontaneously by the window manager, or as a response to an earlier requested move/resize via the Qt APIs. There is no need to call this function from the window manager callback, instead call QWindowSystemInterface::handleGeometryChange().
The position(x, y) part of the rect might be inclusive or exclusive of the window frame as returned by frameMargins(). You can detect this in the plugin by checking qt_window_private(window())->positionPolicy.

This function is called to enable native child window in QPA.
It is common not to support this feature in Window systems, but can be faked. When this function is called all geometry of this platform window will be relative to the parent.

Reimplemented in subclasses to show the surface if visible is true, and hide it if visible is false.
The default implementation sends a synchronous expose event.
