osm

This is a ToDo-Issue.

Following events should be added:

• while moving the hintMarker a event should be fired like move or change. For example, while drawing the rectangle, the current bounds / latlngs can be useful. see #1072
• While moveing / editing the coords of a layer, we can send a coordsmove event. Edit, Drag, Rotation, ...
• Enabledrag & disabledrag in Dragging.js

Describe the bug
adm0_{l,r} tags show up on regular boundaries at z5 but the demo shows them at z4 on maritime boundaries derived from OSM data and not natural earth.

To Reproduce
Steps to reproduce the behavior:

1. Generate a world map with basemap profile including Z4
2. Inspect the generated tiles

**Expected beh

Hi,

I have a huge collection of photos, and think it would be nice to get back to the last position in image list when reopening the app, some kind of session restore in a way.
Thanks a lot for your work

e.g. as per https://wiki.openstreetmap.org/wiki/API_v0.6#Details_of_multiple_users but idiomatic to how the codebase already works.
