[vtkusers] 3D text under parallel projection

[Ming Xie]

Hi All,

I use vtkVectorText and vtkFollower to display 3d labels so that they always
face the viewer. This works fine under perspective projection. When I set
the camera projection to parallel, however, the labels appear backwards
(rotated 180 degrees about the vertical axis). Anybody knows how to fix the
problem?

Thanks,

Ming
