A route planned in Google My Maps or Google Earth can now become a tour
without converting it to GPX first. The import button and a file dropped on
the tours workspace take .kml and .kmz files beside .gpx, through the same
preview, the same import routes and the same transaction as a GPX file.
The preview shows every line of the file on its own, numbered, with its
distance and heights; two lines of one placemark are numbered after its name
and never joined. Heights count only where they are heights: kept for an
absolute line, dropped for any other altitude mode and for the all-zero
placeholder My Maps writes, so a missing height stays unknown. What the file
holds besides its lines (pins, areas, overlays, links to other files) is
counted in a dashed card, and nothing is fetched from elsewhere.
The KML reading reuses the place import's codec. A KMZ only ever has its KML
entry unpacked, counted byte by byte against the decompressed cap whatever
its header claims. A file that cannot be read is refused with its reason
(damaged, an archive without KML, too large unpacked), and the toast names
the file and the reason. A KML or KMZ import keeps the gpx origin of a file
import; its provenance names the real format from the stored file name.
Prettier on every new or moved file that was not formatted, so lint:format
holds them; the files taken off the format baseline are the ones that moved
or were formatted on the way.
