Set the Alt key state in vtkRenderWindowInteractor
Control and shift key state was set in vtkRenderWindowInteractor from QVTKInteractorAdapter, but the state of the alt key was not. This patch addresses that oversight. Hat tip to Mengda Wu <email@example.com> for providing a patch on the VTK users mailing list that describes the needed fix.
