That'd be great, thanks.

While you add it, can you add a FindCell(double[3]) convenience function?

The interface is crazy if all you want is the cell id.

int vtkImageData::FindCell(double p[3])
{
 int subId;
 double pcoords[3] = {0,0,0};
 double weights[8];
 return image->FindCell(p, NULL, 0, epsilon, subId, pcoords, weights);
}
