Summary0011535: File Series Reader does not update extents
DescriptionWhen using a series reader, the output extent of each of the files in
the series is the same even if all of the files in the series do not
actually have the same extent. It seems like there is an assumption
made somewhere that all of the images will have the same extent. The steps to
reproduce using the attached archive are:

// Broken
1) Open the BlankedCorrelation image in Paraview and change to a 3D view
2) Open the BestPatch_* images as a series.
3) Click "Next frame"
4) Observe that the second patch is in the same position as the first
(this is incorrect, they are supposed to be in different positions)

// Works properly
5) Delete the BestPatch_* from the pipeline
6) Open BestPatch_0000 and BestPatch_0001 separately.
7) Observe that they are in different positions (as they are supposed to be).

I suspect the problem is actually not with the file series reader but in the way the pipeline operates. The whole extent is reported by RequestInformation, and that information is used to build the actual extents used in the partitioned data. The problem is that RequestInformation is not called unless the reader itself is modified. If only the time step changes, the RequestInformation step is skipped (which is usually the right thing to do).
