[vtkusers] deleting data arrays after SetXCoordinates

[tom fogal]

Hi all, I couldn't seem to find the implementation for
vtkRectilinearGrid::SetXCoordinates. It's declared virtual but does not force
derived objects to implement the function, so I'm a little curious as to
where it shows up...

Anyway, my main question is if I can delete the array used in SetXCoordinates
(and its Y, Z counterparts) after I have passed them into the function -- does
the function copy all the data over or just save the pointer to the array
given?
