Please see this branch for all of the changes for 2015 that I've seen so
far:

    https://gitlab.kitware.com/vtk/vtk/merge_requests/446

It includes the fix for IOEnSight. Testing welcome (our 2015 buildbot is
low priority in scheduling since it is known to not work, so it takes
time to come back with results).
