[vtkusers] a bug in vtkOpenGLProjectedTetrahedraMapper

[Andy Bauer]

Hi Jin,

Thanks for looking into this. Some instructions for contributing code to
VTK are at http://www.vtk.org/Wiki/VTK/Git/Develop. After you push your
code to gerrit for review, you'll want to assign a reviewer. People that
modified that code are most appropriate. Assign them at the change AND
topic level in gerrit to make sure they get notified by email for the code
review request -- it's a bit clunky and people haven't always gotten emails
for code reviews if you just add them under one of change and topic but I
can't remember which one doesn't send the email.

Regards,
Andy
