I have form setup to perform designing of a form.  There's a toolbox that
you can design from and everything.  However, one thing I can't figure out
how to do is manually add an item to be designed.  Let's say that I want to
add a TextBox to this.  How do I go about this?  Do I need to use the
IDesignerHost, IRootDesigner, or what do I need to do?

And perhaps I'm going about this in the wrong way, but we're going to allow
users to layout a custom form themselves.  And we'll control the basic
elements such as the location and such.  And then I want to manually add
these to the design surface.  Let me know if there's an easier way to do
this such as serializing and deserializing.  I'm sure there is, but I can't
exactly find the articles for doing this.
