Subject: Improve zoom level selection when invoking Potlatch on an object
X-Git-Tag: live~5125
X-Git-Url: https://git.openstreetmap.org/rails.git/commitdiff_plain/50fafa14f86a9ff02458c1e055f24c199f14a8eb

Improve zoom level selection when invoking Potlatch on an object

When invoking Potlatch on a node/way/relation object we should
normally have valid location information in the map parameters, so
use any zoom which is there if possible, otherwise fall back to an
object type specific default value.

Fixes #605.
