[vtkusers] Possible bug in vtkCaptionActor

[David Lonie]

Hi Rafael,

Thanks for the report. The text rendering engine in VTK has been rewritten
recently. Which version of VTK are you using to run this example? I've
tried your script on the current development version and it looks like this
issue has been fixed (see http://imgur.com/HIeVwtz).
