[vtkusers] vtkInteractorStyleImage::SetImageOrientation

> There are just a couple things out of order:

> Move the renderWindowInteractor->SetInteractorStyle( style ); line to

> to the interactor.
>
> Don't call style->SetImageOrientation(leftToRight, bottomToTop); until
> after you have called ResetCamera().  The call to ResetCamera() moves
> the FocalPoint to the center of the data set, and it is usually best
> to do this centering first, before doing anything else to the camera.
> Having the data set centered ensures that the clipping range can be
> properly computed.
>
> Also the first call to ResetCamera (the one after AddViewProp) can be
> removed, since you have added a ResetCamera later in the file.
