[vtkusers] to inherit a class

[Amy Squillacote]

Hi Diego,

Did you include CvtkWin32OpenGLRenderWindow.h in 
your .cpp file?  (I'm guessing this is a subclass 
you created of vtkWin32OpenGLRenderWindow.)  Also 
vtkSetWindowLong is #define'd inside a few 
classes in VTK/Rendering, so you can't just use 
it; you would need to set the up the #define 
appropriately.  (See 
vtkWin32RenderWindowInteractor.cxx around line 50 for an example.)
