Request that the size of a window's client area be set.
If the window is in a fullscreen or maximized state, this request has no effect.
To change the exclusive fullscreen mode of a window, use SDL_SetWindowFullscreenMode().
On some windowing systems, this request is asynchronous and the new window size 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 size changes, an SDL_EVENT_WINDOW_RESIZED event will be emitted with the new window dimensions. Note that the new dimensions may not match the exact size requested, as some windowing systems can restrict the window size in certain scenarios (e.g. constraining the size of the content area to remain within the usable desktop bounds). Additionally, as this is just a request, it can be denied by the windowing system.
