2일 정도 자료를 찾아 보고 했지만.
WebBrowser 는 왜 WPF의 렌더링 방식과 차이가 있는지 모르겠다.
왜냐하면 WebBrowser 위에 다른걸 그리고 싶었지만.
되지 않더라..

그래서 자료를 보다 보니. BitmapSource 라는걸 사용해서 WPF의 렌더링 방식에
맞출수 있다는걸 알았다.
뭐 용어는 잘 모르겠고 암튼 이런 방식인게다. 쩝..
산넘어 산인거지..

우선 이걸 해결 하고 나니 몇가지 더 테스트 할게 남아 있다.
실제 WebBrowser는 숨겨 놓고 Image 같은데 실시간으로 뿌리면서 드로잉 해야 한다는 것과
숨겨 놓은 웹의 Mouse, Keyboard 등의 접근을 또 어떻게 처리 해야 하느냔데..

암튼 더 고민해봐야 할듯 하다.
아래 자료는 최종 코드...
