[osg-users] DEEP_COPY_USERDATA isn't that deep

[Robert Osfield]

Hi Chris,

My guess is that the deep copy support wasn't built in when I wrote it.
Different parts of the OSG developed at different points so sometimes you
get little inconsistencies.  Feel free to modify the code to do a deep copy
when requested and generate a PR for it.

Robert.
