Invalidates the window's surface by releasing its surface buffers.
Many platforms do not support releasing the surface memory, and the default implementation does nothing.
The platform window is expected to recreate the surface again if it is needed. For instance, if an OpenGL context is made current on this window.

Reimplement to let Qt be able to request activation/focus for a window.
Some window systems will probably not have callbacks for this functionality, and then calling QWindowSystemInterface::handleFocusWindowChanged(QWindow *w) would be sufficient.
If the window system has some event handling/callbacks then call QWindowSystemInterface::handleFocusWindowChanged(QWindow *w) when the window system gives the notification.
Default implementation calls QWindowSystem::handleFocusWindowChanged(QWindow *w)

Implements QOpenGLCompositorWindow.
Definition at line 106 of file qeglfswindow.cpp.
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.
