[vtkusers] vtkDICOMImageReader results,..

[Miguel Angel Rodriguez Florido]

	Well, I was seeing your code, when I had an idea to check before update
my VTK.

	I saw that you check the image scalar range. I did it, and I got "0
1",..ahahahah!! (light :-)). I din't have an "Update", so the class was
losing the scalar range.

	So, adding the "Update" method to the reader, it works perfectly!!!.

	Thank you very much.

	Best.
