[Paraview] ParaView and QT

[Berk Geveci]

In a way, I suppose. However, keep in mind that VTK and ParaView
release cycles are completely different. VTK is released at most once
per year (and it is almost a miracle when that happens) whereas
ParaView is released 3-4 times per year. If we were stuck with the
latest version of VTK (5.0 from 2 years ago), we would end up bundling
a lot of improvements and bug fixes for VTK in ParaView. This would
make the development a major pain and the migration of improvements
from ParaView to VTK would almost never happen. Maybe one day, if the
release cycles are close AND VTK is as widely distributed as Qt, we
can stop bundling VTK.
