interaction of linejoin/linecap/approximation_scale on rendering perf in mapnik when drawing lines
# line symbolizer on 10m-admin-0-countries.shp
* linejoin can double line rendering times
* approximation scale can mostly avoid, but ideally don't use linejoin unless absolutely necessary
## default line symbolizer
$ howfast.py world_merc.xml 10
