// Revision: 0.9
// Purpose: Open and understand it
//
// CHANGELOG
// 0.8 to 0.9 :
//  - finally discovered where letter pages and nav bar pages are stored!...
// 0.7 to 0.8 :
//  - fixed some variables
// 0.6 to 0.7 :
//  - cleaned up a bit some old unused variables
//  - changed some variables and some code
//  - again new informations dicovered
// 0.5 to 0.6 :
//  - changed some var types
//  - pages are now read directly from the pointer's array (easier to read)
// 0.4 to 0.5 :
//  - discovered pointers!
//  - decoded some items types
//  - decoded some variables
//  - decoded frames
//  - renamed enditem by actionitem
// 0.3 to 0.4 :
//  - changed variable names to unique names
//  - added open=suppress to IDSTRINGS and quotes to ReadIdWord to permit clean CSV export
//  - added possible values
//  - replaced ushort by short
//--------------------------------------
//
// Note: Every x and y positions are counted from 1.
//       Every pointer is counted from 0.
//       Every "idword" is counted from 1.
