*
* History:
*   2002-03-04 V3.1
*          Add codes to demostrate the use of CMovingBitmap::ShowBitmap(CMovingBitmap &).
*	 2004-03-02 V4.0
*      1. Add CGameStateInit, CGameStateRun, and CGameStateOver to
*         demonstrate the use of states.
*      2. Demo the use of CInteger in CGameStateRun.
*   2005-09-13
*      Rewrite the codes for CBall and CEraser.
*   2005-09-20 V4.2Beta1.
*   2005-09-29 V4.2Beta2.
*      1. Add codes to display IDC_GAMECURSOR in GameStateRun.
*   2006-02-08 V4.2
*      1. Revise sample screens to display in English only.
*      2. Add code in CGameStateInit to demo the use of PostQuitMessage().
*      3. Rename OnInitialUpdate() -> OnInit().
*      4. Fix the bug that OnBeginState() of GameStateInit is not called.
*      5. Replace AUDIO_CANYON as AUDIO_NTUT.
*      6. Add help bitmap to CGameStateRun.
*   2006-09-09 V4.3
*      1. Rename Move() and Show() as OnMove and OnShow() to emphasize that they are
*         event driven.
*   2006-12-30
*      1. Bug fix: fix a memory leak problem by replacing PostQuitMessage(0) as
*         PostMessage(AfxGetMainWnd()->m_hWnd, WM_CLOSE,0,0).
*   2008-02-15 V4.4
*      1. Add namespace game_framework.
*      2. Replace the demonstration of animation as a new bouncing ball.
*      3. Use ShowInitProgress(percent) to display loading progress. 
*   2010-03-23 V4.6
*      1. Demo MP3 support: use lake.mp3 to replace lake.wav.
