//-------------------------------------------------------------------
// VERSIONS :
// 1.0  : Initial release
// 1.1  : + : Added unit in the constructor
//        + : Now Positions start @ (1,1).. then the first image @top-left of a page is (1,1)
//        + : Added in the description of a label :
//                font-size    : defaut char size (can be changed by calling Set_Char_Size(xx);
//                paper-size    : Size of the paper for this sheet (thanx to Al Canton)
//                metric        : type of unit used in this description
//                              You can define your label properties in inches by setting metric to 'in'
//                              and printing in millimiter by setting unit to 'mm' in constructor.
//              Added some labels :
//                5160, 5161, 5162, 5163,5164 : thanx to Al Canton : acanton@adams-blake.com

//        + : Added 3mm to the position of labels to avoid errors
// 1.2  : + : Added Set_Font_Name method
//        = : Bug of positioning
//        = : Set_Font_Size modified -> Now, just modify the size of the font
//        = : Set_Char_Size renamed to Set_Font_Size
