Looks all good to me. Can you confirm it does what you want, in other words,
that you can remove the 'update_image_data' from your code.

Cheers,

Actually, I have just realized that this code can be tested. It would be great
if you could add a test, eg to enthought/mayavi/tests/test_array_source.py. We
are trying to have as much test coverage as possible. It has proven very useful.

Also, the existing tests are broken by your patch. I haven't had time to check
if it is just noise, or actual problems. You can run the test suite using
'mayavi2 -t'.
