This is useful for knowing what threshold length might be set via +n<threshold>. Currenlty the user would not necessarily know that.

…ls#177) LibGMT no longer takes a pathname as input. The library path is either just the file name, or the directory is taken from the GMT_LIBRARY_PATH environment variable. This allows users to direct the GMT/Python to libgmt. It's useful to test against a local build of GMT trunk or resolving path issues without resorting to LD_LIBRARY_PATH. Replace section on LD_LIBRARY_PATH with GMT_LIBRARY_PATH in install docs. Make it clear that this should be a last resort. Fixes GenericMappingTools#172 and fixes GenericMappingTools#165

This is useful for knowing what threshold length might be set via +n. Currently the user would not necessarily know that. With -Vl we print the min, max, and mean scaled vector lengths. For geographic geo-vectors these are in km while for Cartesian vectors they are in the selected length unit (inch, cm, points).
