Allow interop with Windows Forms controls


Provide a DrawingElement derived class that allows hosting of a Windows Forms control - including panel controls which themselves contain any number of nested controls. The Windows Forms control assignment and declaration should be supported by the XAML renderer.
Example usage is to integrate a System.Windows.Forms.TextBox control into the view and have it position correctly in regards to the DrawingElements. Rotation will not be supported - and only limited support for scaling (if any).
