[Paraview] number of points in the Information tab

[Cory Quammen]

Weiguang,

Points are duplicated for the polygons defining the end caps so that a
separate normal for the end cap can be specified - it's a common computer
graphics technique to get sharp edges where desired. Uncheck the "Capping"
property and your source will have 20 points as you probably expected (but
no end caps).

If the point duplicating weren't done, the cylinder would look funny at the
ends. Try running the Clean filter on the cylinder to see what it would
look like. This merges the duplicate points.
