*.===========>
*.
*.   This routine draws a frame boxe . The frame is drawn according to the
*. current fill area attributes .
*.
*. _Input parameters:
*.
*.  INTEGER X1,Y1 : Left down corner coordinates of the inside boxe
*.                  of the frame .
*.  INTEGER X2,Y2 : Right up corner coordinates of the inside boxe
*.                  of the frame .
*.  INTEGER X3,Y3 : Left down corner coordinates of the outside boxe
*.                  of the frame .
*.  INTEGER X4,Y4 : Right up corner coordinates of the outside boxe
*.                  of the frame .
