[osg-users] Strange node mask behaviour since 2.0

[Art Tevs]

Hi Robert.

Thanks, this helps. 

Hmm, I have already tried to add similar lines to the
code, but I have added setTransversalMask(saved_mask)
after the setCullSettings(saved_cull_settings) and not
before. Probably therefor I was not able to correct
the Problem by myself.

Thank you again.

Best regards, Art
