System.Windows.Forms.Textbox
Imagine a multiple line text box that never gets focus. For instance
the conversation box of a chat screen.
How can you keep it scrolled to the bottom as lines are added.
Textbox.ScrollToCaret() requires the control be in focus and I would
rather not be swapping around focus while users are, well, using.
