Passing STL objects across library boundaries has other problems.  Only
recently was the C++ ABI standardised and many compilers to not (fully)
conform to it.  That means that if you build the VTK libs with compiler
X and you build an app that uses them with compiler Y it might not
link.  And that's on any OS.  gcc has the -Wabi warning to catch some
such problems.  (As a library, VTK probably should compile cleanly with
that warning on, but I forget if it does.)
