[vtk-developers] PNGWriter now writing out a black background after 17 Oct.

[Andrew Maclean]

Hi All,

Sometime after 17 October something changed and the combination
of vtkWindowToImageFilter and vtkPNGWriter no longer writes out an image
with a coloured background.

vtkWindowToImageFilter.* was last changed Sept 24 2016.
vtkPNGWriter.* was last changed Sept 24 2016.

So the change is not in these files.
I also attach some test code so people can verify this. Apparently this is
not picked up in testing.
