Corners of a rectangle
Returns the four corners of a rectangle
corners(window)
This trivial function is occasionally convenient.
If window is of type "rectangle" this returns the
four corners of the window itself;
otherwise, it returns the corners of the bounding rectangle
of the window.
A list with two components x and y, which are numeric
vectors of length 4 giving the coordinates of the four corner points
of the (bounding rectangle of the) window.
