I pushed a small documentation addition to Gerrit - would this have
clarified it for you?

Also, there are no manuals. Writing a manual for such a fast changing
library is very hard. Instead we must depend on keeping the documentation
updated, as we are doing here. Additionally, examples are key. Please
add/modify examples on the wiki: http://www.vtk.org/Wiki/VTK/Examples/Cxx if
you find something that is missing or unclear.
