Summary0012170: Precision problem with .vtp files
DescriptionI am finding really strange results when trying to visualize the following dataset. ParaView Trunk, local server, Windows (known to occur on Linux).

Insert the following into a file called test.vtp.

<?xml version="1.0"?>
<VTKFile type="PolyData" version="0.1">
  <PolyData>
    <Piece NumberOfPoints="3" NumberOfPolys="1">
      <Points>
        <DataArray type="Float64" NumberOfComponents="3" format="ascii">
           -7.5445544554e-02 -1.0048351648e-03 8.9374551773e+03
           -7.3433663366e-02 -1.0048351648e-03 8.9374551773e+03
           -7.3433663366e-02 1.0048351648e-03 8.9374551773e+03
        </DataArray>
      </Points>
      <Polys>
        <DataArray type="Int32" Name="connectivity" format="ascii">
           0 1 2
        </DataArray>
        <DataArray type="Int32" Name="offsets" format="ascii">
  3
        </DataArray>
      </Polys>
    </Piece>
  </PolyData>
</VTKFile>

Now, open this data and rotate it. It will jitter, and jump all over the place. Assuming ParaView is using doubles internally, this should not happen.

Still weird and bad. However, it now comes up in 2d - you have to flip viewport to 3d to see the issue.
