[vtkusers] Changing vtkStructuredPoints scalar type

[Robb Brown]

I have a vtkStructuredPoints file with ScalarType set to unsigned 
char.  I want to convert this file so that ScalarType is short.  How 
would I do this?  I tried reading it, using SetScalarTypeToShort() 
then writing it and I do get a larger file but upon reading the file 
again GetScalarTypeAsString still reports unsigned char.

Thanks,

Robb
