A Windows-specific class that can create and embed an ActiveX control inside
itself.
To use it, create one of these, put it in place and make sure it's visible in a
window, then use createControl() to instantiate an ActiveX control. The control
will then be moved and resized to follow the movements of this component.
Of course, since the control is a heavyweight window, it'll obliterate any
JUCE components that may overlap this component, but that's life.
