Description
Returns an object of the class <bounding-box> with the edges specified by x1, y1, x2, and y2. x1, y1, x2, and y2 are canonicalized in the following way. The min point of the box has an x coordinate that is the smaller of x1 and x2 and a y coordinate that is the smaller of y1 and y2. The max point of the box has an x coordinate that is the larger of x1 and x2 and a y coordinate that is the larger of y1 and y2. (Therefore, in a right-handed coordinate system the canonicalized values of x1, y1, x2, and y2 correspond to the left, top, right, and bottom edges of the box, respectively.)
This is a convenient shorthand function for make(<bounding-box>, left: top: right: bottom:)
