Re: type casts (FindWindow)

This goes back to when I was asking about RTTI and wxWindows.

The method, Object::CreateFromObject is used to look up the wxWindow
object type using a typemap similar to the one used with
Event::CreateFrom.

The only difference is that the one in Object uses the class's type
information.

I realize now that this is only a temporary solution, since the typemap
is unaware of sub-classed controls.  I'm not sure of a good way of
getting around this.

One possible solution would be to keep a static Hashtable of all the C++
objects, and their associated C# objects.  Then in the constructor of
Object, add the references to the static Hashtable:

	classtable.Add(wxObject, this);

Then use this whenever we need a reference to a C++ object:

        Object o = classtable[classptr];

The problem in doing this, is that there isn't much of a way for us to
tell which C++ objects have been removed, and which ones are still
needed.

Any ideas?
