Options 

DirectX plugin changes:
- The Win32 GetMessage function has been isolated in a thread. This has
    been done because this function can block the thread. Thanks to this
    change, you can now move your window without any video and audio
    interruption.
- Splitted the events handling code into a separate file.
- Fixed the bug associated with the window dragging option in the
    diplay properties.
