[OSM-talk] colour fills in osmarender

[Andy Robinson]

Totally agree Richard, at its simplest, a way is currently defined as:

"A way is a list of line segments that describe a street, or similar. The
way can be in any form, and segments can be members of lots of ways."

It was always intended was it not that what we developed as a "way" was just
a collection of segments. Nothing more implied. So at the moment thus they
can be used for whatever you like and a route on the national cycle network
is just as valid as the segments making up a street or the route taken by
the number 69 bus.

Cheers

Andy
