If the window is in an exclusive fullscreen or maximized state, this request has no effect.
This can be used to reposition fullscreen-desktop windows onto a different display, however, as exclusive
fullscreen windows are locked to a specific display, they can only be repositioned programmatically via
SDL_SetWindowFullscreenMode().
On some windowing systems this request is asynchronous and the new coordinates may not have have been
applied immediately upon the return of this function. If an immediate change is required, call
SDL_SyncWindow() to block until the changes have taken effect.
When the window position changes, an SDL_EVENT_WINDOW_MOVED event will be emitted with the window's new
coordinates. Note that the new coordinates may not match the exact coordinates requested, as some
windowing systems can restrict the position of the window in certain scenarios (e.g. constraining the
position so the window is always within desktop bounds). Additionally, as this is just a request, it can
be denied by the windowing system.
