[vtkusers] Problem QVTKWidget using vtkCarbonRenderWindow instead of vtkCocoaRenderWindow

[Clinton Stimpson]

That's the right flag, QT_MAC_USE_COCOA.  It is initially set in 
qconfig.h, which is generated by the configure script, and only forced 
on in qglobal.h if building 64 bit.
I've attached a patch for you.  How far does that get you?
