SDL_SetWindowPosition respects display num for SDL_WINDOWPOS_CENTERED_DISPLAY. This allows for this kind of code in an application: int monitorID = 1; // the second monitor! SDL_SetWindowPosition(sdlWin, SDL_WINDOWPOS_CENTERED_DISPLAY(monitorID), SDL_WINDOWPOS_CENTERED_DISPLAY(monitorID)); Fixes Bugzilla #2849.
