// To demonstrate the Union feature, we'll draw a Cyan rectangle
// around both the draggable rects.
Var u As Rect = rectone.Union(recttwo)
buffer.Graphics.DrawingColor = CyanColor
buffer.Graphics.DrawRectangle(u.Left, u.Top, u.Width, u.Height)
theSize = u.Size
Var theTop As Point = u.Top
i = theTop.x
j = theTop.y
