[vtk-developers] Some changes related to DeepCopy..

[Will Schroeder]

Hi Folks-

I've made a couple of changes related to DeepCopy and want to give everyone 
a heads up in case there is strange behavior. vtkPointSet was creating new 
points not of the same type as what was being copied. Now MakeObject() is 
used to produce the same type. vtkDataArray was using a generic float 
interface to copy data arrays of different types (the subclasses handle 
copying data of the same type). I added a doubly-templated process to do 
the copying now. I also found that vtkIdTypeArray was not doing the 
DeepCopy correctly when input and output types were the same type and was 
falling back on the slow, generic float API. Now it uses memcpy and should 
be faster.

Please let me know if you encounter anything strange.

Will
