내용이 부실한데 드래그를 구현하려면 down 이벤트를 보고 해당 버튼의 마스크가 사라질때 까지 보고 있어야 할 듯?
uinput에서 그럼 드래그 어떻게 구현해야 하냐... ㅠㅠ

키보드의 경우 키 다운, 업 이벤트가 오는 것 같고, 반복키 처리를 좀 찾아봐야 할 듯.
마우스는 buttonmask에

relative / absolute mode 관련 참고할 코드
doptr() 에서 현재 좌표 넘어온 것과 이전 마지막 좌표 계산해서 넣는것 외에는
libvncserver 자체에서 상대좌표 모드로 작동하진 않도록 구성되어 있는 것으로 보인다.
