[OSM-talk] Legend add-in for osmarender

[Etienne]

Steve
It looks very nice.

It ought to be possible to generate the legend as an integral part of the
main Osmarender process so that you don't have to make a separate .png
file.  If I get a quite moment I'll see if I can figure out what you'd need
to do.

To get everything lined up you could just post edit the .osm file and set
the lat/lon values manually in fixed size increments (near lat=0 to avoid
distortion from the Mercator projection).
