Viking: has

(different from measure tool.)

Also put the compass rose in the same corner as the scale bar, that way we won't need to make larger screenshots if we want to capture both.

Or allow repositioning, of both the scale bar and the (future) compass rose.

Can you believe I had to make my own north arrows. Do not laugh.

$ cat Makefile
north_arrow.csv:north_arrow_0.csv
    ogr2ogr $@ $< -sql 'SELECT Name FROM "$(basename $<)"' -lco GEOMETRY=AS_WKT \
    -ct '+proj=affine +xoff=4 +yoff=13'
north_arrow_0.csv: Makefile #A movable north arrow (compass rose)
    echo WKT,Name > $@
    echo '"LINESTRING (0 0,0 4,-.5 3,.5 3)",北' >> $@
%.kml:%.csv
    ogr2ogr -f LIBKML ...

Anyway, the compass rose is the single lacking feature stopping users from printing out maps that can be used for official business...
