Remarks
Despite the name and signature, this method sets the brightness of the entire display, not an individual window. A window is considered to be owned by the display that contains the window's center pixel. (The index of this display can be retrieved using SDL_GetWindowDisplayIndex().) The brightness set will not follow the window if it is moved to another display.
