[vtkusers] vtkStreamLines and vtkMultiBlockDataSet

[Bill McGrory]

Can someone tell me whether I should be able to compute streamlines from
a structured 3-d multi-block dataset such that the streamlines cross
block boundaries, when I set as input to a vtkStreamLine filter a
vtkMultiBlockDataSet?

I'm using the cvs version.
It appears to me that vtkStreamer is passed the vtkDataSet of the last
block in the dataset, such that streamlines are restricted to that
domain.

Thanks for any assistance
Bill
