[vtkusers] vtkCaptionActor2D text appears chopped

[David Lonie]

Hi Roberto,

We've recently fixed a number of bugs in the text rendering code in the
development branch. I'm adding your test case to our regression tests to
check if we still see this with the new rendering backend.

Which version of VTK are you seeing this in?

Dave
