[vtkusers] vtkImageResliceMapper problems

[David Gobbi]

Hi Ang,

I was able to reproduce the bug by using the OpenGL2 backend,
and I have an idea about where the code has to be fixed.

Luckily, there is something that you can do while you wait for the
fix: add this to your code after you create the vtkImageResliceMapper:

    resliceMapper->AutoAdjustImageQualityOff();

That should work as a temporary work-around.
