//-------------------------------------------------------------------
// 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 : hide@address.com
//				8600 						: thanx to Kunal Walia : hide@address.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
