[vtkusers] Texture Mapping with 2D Texture Coordinates

[Wenlong Wang]

Yes, I did set the number of components and number of tuples explicitly.
However, the texture is not positioned right.

I think it because I used a picture which doesn't belong to the dataset.
So, my question is, should I process the image in some way before I map it
onto the model? if so, what should I do?

Thank you very much.
