Rectangle.

You will find a general example for the use of rect here.

Rectangle. The module defines a rectangle object and some basic rectangle functions.

static Rect rect::alloc()

w, h float, float - Size of rectangle, result is (0.0, 0.0, w, h)
Rectangle
left, top, right, bottom float, float, float, float - Co-ordinates of rectangle. The data are not normalized!

    Rect		intersect	= rect::alloc (); 
    Rect		union_		= rect::alloc ();

    rect::intersection (intersect, r1, r2);
