[vtkusers] Why does the vtkRenderLargeImage open an other window?

[John Biddiscombe]

I seem to recall that RenderLargeImage switches to offscreen rendering - 
which on some platforms causes a new (supposed to be invisible, but 
sometimes not) window to be created - but this was fixed recently in 
CVS. I may be wrong, but try doing a cvs update and see if the problem 
goes away.
