   Description:
   class XQtCards is a QPixmap factory for card images, to be used by
   XPat2 and other card games.
   This class does mainly exist to separate the ugly image constructor
   from the rest of the game.

   Sources:
   XQtCards.h		header file
   XQtCards.cpp		implements the constructor and destructor
   XQtCardsDlg.cpp	implements the customisation dialog

   Dependencies:
   requires the widget qmaskedit and the Qt library (tested with version 1.42)
