[vtkusers] Probably Bug in vtkCharArray

[Samson Timoner]

I'm not getting cvs stuff, but here is what I think is a bug in vtk4.0
which has not been fixed according to what is on the web site:

vtkCharArray::DeepCopy(vtkDataArray *)

If you send this command a vtkIntArray, it does a memcopy.
I assume this is not the right thing to do. You instead want
to convert each int to char, one int at a time.

Every other class does the right thing.  vtkBitArray, vtkDoubleArray,
vtkLongArray, etc. all copy one element at a time when the element is a
different type. (they do a memcopy when the element is the same type) 
In fact, vtkUnsignedCharArray has it right.

I'm not sure if I have found a bug or if someone decided to be inconsistent
on purpose. But, I'm guessing bug.

The Fix: Just use the DeepCopy command in any of the other classes. 
Only the memory allocation line and the memcopy line differ.

 Cheers,
