WIP: Support 9.5.2

[larsoner]

Trying to add support. Now I see:

_________________________________________________________________ TestArraySource.test_2d_data _________________________________________________________________
mayavi/tests/test_array_source.py:102: in test_2d_data
    sc1 = surf.actor.mapper.input.point_data.scalars.to_array()
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
E   AttributeError: 'NoneType' object has no attribute 'to_array'

So there is still some bug with defaults
