empty_array is not the only function in array_ext*. The other one is
a function that converts a numpy array to a format suitable for a
vtkIdTypeArray. These are defined in tvtk/src/array_ext_sp.pyx (sp
stands for scipy since this predates the numpy name). So you can use
the source and see what is being done. If you have no need for the id
type array stuff you can easily modify array_handler to use numpy's
empty and it should work.

Easiest way is to use tvtk since it works and is tested.
