[vtk-developers] BUG in vtk[Render/ImageWindow]Widget

Good (or bad) news, this seems to be a VTK "bug", not a Tcl/Tk or a 
framebuffer problem  : the code I sent you works with the 3.1.2 official 
release, but does not with the CVS.

I've checked the last two changes that were made to the widget in the CVS, 
but they do not seem to be involved. I hope it's not too deep in the 
vtk[Win32OpenGL]Image/Render]Window, as I'm not familiar enough with OpenGL 
to poke in it.

Thanks for any clue.
