For the windows version, if running with fullscreen disabled, center the main window instead of creating it top-left all the time.

Also renamed WindowRect to windowRect & PixelFormat to pixelFormat for consistency with other locally declared variables.  (Uppercase should be reserved for class names, ie WindowRect is the class/struct, windowRect is an local object in your code.)
