// ***** Big Modification History Area *****
// LLY.274p, some big modification:
// [1] Rename all MP3 relative info. because module name has changed !!
//  - Module Name w/ "FM_" as it's prefix.
//      (1) General case : only rename "MP3_" as "FM_"
//      (2) Special case : do a little modification for APIs name
//          . MP3_CheckMP3Disc()  -->  FM_CheckPlayableDisc()
//          . _MP3_Prepare()  -->  _FM_PrepareInfo()
//  - Variables Name:
//      . __cMP3AlbumList[]  --> __strFMDirList[]
//      . _cMP3SongList[]  -->  _strFMSongList[]
//      . _dwSongTOC[]  -->  _dwFMFileTOC[]
//      . __pMP3NameList  -->  __pFMNameList
//      . __bMP3Page  -->  __wFMMenuPage
//      . _wSongsOfAlbum  -->  _wFMFilesOfDir
//      . __wTotalAlbums  --> __wFMTotalDirs;
//      . __wTotalSongs  -->  __wFMTotalFiles;
//      . __bMP3MenuID --> __bFMMenuID
//      . __bMP3Page.wAlbumIndex  -->  __wFMMenuPage.wDirIndex
//      . MP3Log  -->  FileLog
//      . MP3_PAGE_BEGIN_ID  -->  _bMenuPage_1stID
//      . MP3_PAGE_END_ID  -->  _bMenuPage_lastID
//  - Define Name
//      . MP3_MENU_NONE  --> FM_MENU_NONE
//      . MP3_MENU_ALBUM  --> FM_MENU_ALBUM
//      . MP3_MENU_SONG  --> FM_MENU_FILE
//      . MP3_MAX_ALBUM_NO  --> FM_MAX_DIR_NO
//      . MP3_MAX_SONG_NO  -->  FM_MAX_FILE_NO_ONE_TITLE
//      . MP3_MAX_STRING_LENGTH  --> FM_MAX_STRING_LENGTH
//      . MP3_NAME_DIR  -->  FM_CONVERT_DIRNAME
//      . MP3_NAME_SONG  -->  FM_CONVERT_FILENAME
//      . MP3_GET_ALBUM_INDEX  -->  FM_QUERY_DIR_INDEX
//      . MP3_1STITEM_OF_PAGE  -->  FM_QUERY_1STITEM_OF_PAGE
//      . MP3_LASTITEM_OF_PAGE  -->  FM_QUERY_LASTITEM_OF_PAGE
//      . MP3_IS_CURRENT_PAGE  -->  FM_QUERY_CURRENT_PAGE
//      . MP3_ALBUM_PAGE  -->  FM_PREPARE_DIRPAGE
//      . MP3_SONG_PAGE   -->  FM_PREPARE_FILEPAGE
//      . MP3_NEW_PAGE    -->  FM_PREPARE_NEWPAGE
//      . MP3_NEXT_PAGE   -->  FM_PREPARE_NEXTPAGE
//      . MP3_PREV_PAGE   -->  FM_PREPARE_PREVPAGE
//      . MP3_NEXT_ALBUM  -->  FM_PREPARE_NEXT_DIRPAGE
//      . MP3_PREV_ALBUM  -->  FM_PREPARE_PREV_DIRPAGE
//      . MP3_SUPPORT_JUMP_ALBUM  -->  SUPPORT_JUMP_ONE_DIR_FOLDER
//      . MP3_NO_SELECTION  --> NO_SELECTION_FOR_MENUPAGE
//      . CONVERT_MP3_NAME  --> CONVERT_UNKNOWN_NAME
// [2] Remove _FM_ChangePage() because it's unnecessary.
//     And _FM_ChangePage(MP3_CURRENT_PAGE, XXX) can be replaced with
//     _QueryInfo(MP3_IS_CURRENT_PAGE)

// LLY2.80, Remove some un-necessary code, ex.
// [1] Define
//     - VCD_SYSTEM
//     - W_MP3
//     - USE_DRAM_BUFFER
// [2] Variables
//     - _bMenuPage_1stID
//     - _bMenuPage_lastID
// [3] MENUPAGEINFO structure, some variables from WORD to BYTE unit
//     - wNOofItems --> bNOofItems
//     - wTotalPages --> bTotalPages
//     - wPageIndex  --> bPageIndex
// [4] Rename some global variables to meet CT908 UI requirement
//     - __strFMDirList --> __pFMDirNameList
//     - __strFMFileList --> __pFMFileNameList
//     - _dwFMFileTOC --> _pFMFileTOC
//     - _wFMFilesOfDir --> __pwFMFilesOfDir
//     - __wFMMenuPage.wDirInex --> __bFMActiveDir
//     - __wFMTotalDirs --> __bFMTotalDirs
//     - bLoc --> __pFMDirLoc

// LLY2.80, re-adjust the define name and let it be readability

// LLY2.81,
// [1] Remove active/ selection info. within MENUPAGEINFO
//     - __wFMMenuPage.wHighLight --> __FMActiveCursor.wIndex
//     - __wFMMenuPage.wSelection --> __FMSelectCursor.wIndex
// Let selection cursor be same as active cursor while support only one cursor case
// The operation:
//     - Light selection cursor:
//       update active info. first, then update selection info. later
//       ie. selection info. means last active info.
//     - Light active cursor:
//       update selection info. first, then update active info. later
//       ie. active info. means last selection info.
//    Thus, F/W can increase the code's readability
//    (ie. less #ifdef/ #else/ #endif SUPPORT_RUNTIME_SELECTION_ACTION)
// [2] Remove some un-necessary code
//     - FM_PREPARE_NEWPAGE
// [3] Remove wOverflow info. within MENUPAGEINFO,
//     Because nobody refer it after modifying KEY_LEFT/ KEY_RIGHT procedure
// [4] Transfer the coordinate from disc view to directory
//     - disc view: the file index is continue from 1st directory's 1st file
//                  to last directory's last file
//     - directory view: always index from '0' for 1st file of each directory
//     - related variables: __wFMActiveCursor.wIndex/ __wFMSelectCursor.wIndex/ __wFMMenuPage.w1stID
// [5] Splite _QueryInfo() into three APIs:
//     - _QueryInfo(bQueryID, wParam) -- only relative to file index
//     - _FM_QueryInfo2(bQueryID) -- independent of directory/ file index
//     - _FM_QueryInfo3(bQueryID, bDir, wParam) -- relative to directory/ file index together

// LLY0.83b-2,
// [1] Add the control procedure for CT908 UI

// LLY0.86, add FM_CLEAR_BACKGROUND for _FM_InitialMenu() reference

// LLY0.86-2,
// [1] Re-adjust program mode relative procedure to meet new program mode (>=WinDVD0.86)
//     - Maintain __bProgramCurrentIndex & __bProgamMaxEntry
//       while insert or delete entry
//     - Index from '1' for __ProgIdxList[].wSubIndex
