s2rectxy
Draw a rectangle in the xy plane at a given z coordinate.
Prototype
void s2rectxy(float xmin, float xmax, float ymin, float ymax, float z);
Description
Draw a rectangle in the xy plane, at a given z coordinate. The rectangle is a filled quadrangle. The edge of the rectangle is NOT drawn. Use s2line if you need a border to your rectangle/s.
