only supports VTK version 5, VTK 6 incompatible?

[aewallin]

Apparently VTK version 6 has some incompatibilities with VTK version 5.

A note should be added that openvoronoi visualization scripts only work with VTK version 5.
or the scripts rewritten so they work on the latest VTK release.

Modified all the python examples for VTK6 in my fork (merged with jtpedersen's SVG fork). Most of them run (on OS X) except for the following:
• hilbert_curve_1_vd.py => endless loop?
• line-segment/lineseg_50_animation.py and point_animation.py => signature mismatch addVertexSite()
• voronoi_10_step_animation.py => getSeedVertex() missing in VoronoiDiagram
• poisson_stat_3.py => 'poisson/N10000_S0.pickle.gz' file not found

[aewallin]

This is merged now.
The problematic example-scripts mentioned above still deserve a look.
