[vtkusers] volume texture support

[Karthik Krishnan]

Assuming your mesh is dense enough, you can probe the imagedata with the
polydata.

See vtkProbeFilter.

This is going to create point data / cell data attributes on your 2D
polydata containing the interpolated scalars from the image data. You would
just color this using a lookup table.
