/**
|

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.
