[vtkusers] vtkTexture::SetInput(ImageData*) method not found

[David Gobbi]

Hi Kyle,

You'll have to include the vtkImageData.h header file.

Without this header file, the compiler doesn't know that
vtkImageData is a subclass of vtkDataObject.

That code comment in vtkTexture is out-of-date, I'll
remove it.
