Contains just a structure with these following parameters :

   nX and nY : position of the upper left corner of the area

   nWidth and nHeight : dimension of the area

   nLeftDecoration, nTopDecoration, nRightDecoration, nBottomDecoration : tickness of the decoration of the area

Maybe use everytime a window is drawn or redrawn.
