Description:
SUBROUTINE PGRECT (X1, X2, Y1, Y2)
REAL X1, X2, Y1, Y2
This routine can be used instead of PGPOLY for the special case of
drawing a rectangle aligned with the coordinate axes; only two
vertices need be specified instead of four. On most devices, it is
faster to use PGRECT than PGPOLY for drawing rectangles. The
rectangle has vertices at (X1,Y1), (X1,Y2), (X2,Y2), and (X2,Y1).
Arguments:
X1, X2 (input) : the horizontal range of the rectangle.
Y1, Y2 (input) : the vertical range of the rectangle.
