33 A Windows-specific class that can create and embed a HWND inside itself.
35 To use it, create one of these, put it in place and make sure it's visible in a
36 window, then use setHWND() to assign a HWND to it. The window will then be
37 moved and resized to follow the movements of this component.
39 Of course, since the window is a native object, it'll obliterate any
40 JUCE components that may overlap this component, but that's life.
