[vtkusers] OffScreenRendering Text

[Karthik Krishnan]

Is this using a vtkImageMapper and a text annotation on top of each other.
That would be weird. Both lie on the overlay plane. The renderer is going to
render them in the order in which they are added.

Try using a vtkImageActor to render your image and the text (using
vtkActor2D-vtkTextMapper) over that and let us know if the problem persists.
