[josm-dev] [PATCH 02/24] Give OsmDataLayer a bounds() function

[Dave Hansen]

We'll use this in the validator to figure out whether a particular
node is truly the end of a series of ways, of if it may just not
have downloaded other ways touching this node.

Think of coastline validation.  The coastline isn't allowed to
end, but it is ok to end if it is outside the downloaded area.
