/SquaXStr   {{ x_count }} def         % hor number of thin lines between strong ones
/SquaYStr   {{ y_count }} def         % ver number of thin lines between strong ones

% line width and color for thin lines

/SquaYSta PattTrasY SquaYLen div cvi neg def

% ending vert and hor line num
/SquaXEnd SquaXNum SquaXSta add def
/SquaYEnd SquaYNum SquaYSta add def
