[vtkusers] updating texture on a plane

[Yoan BLANC]

Hi

I've got this pipeline :

                  vtkImageReslice v
                             vtkTexture v
vtkPlaneSource > vtkPolyDataMapper > vtkActor

And I want to update the Z slice of the texture (into the imageReslice). 
The problem is that the texture isn't modified.

I've tried these modifications :

vtkImageReslice::SetOutputExtent()
vtkTexture::SetInput()
vtkActor::SetTexture()

Cheers.

Yoan
