Can you rebase please

[fgravin]

If one day we want to edit a real feature (from WFS), edit its attributes for example. Would it be in same directive ?
Is the name editFeature is well chosen ?

[sbrunner]

Just one issue I see, the measure should be rounded at 3 significant digits :-)

[adube]

• Rebase: OK
• Multiple selection: No
• Rounded at 3 significant digits: What do you mean ?

[sbrunner]

For example display 591 km instance of 591.54 km in the panel and on the map when the "Display length" is checked, finally the same as the tooltip that's display while drawing :-)

@fgravin Ready for merge.

[pgiraud]

@sbrunner "561 km" already has 3 significant digits. Other examples are 5.42 km or 48.6 km or 7520 km.

[sbrunner]

@pgiraud yes it's what's I say, but we get 591.54 km that have 5 significant digits ...

[sbrunner]

We will get, now it's corrected :-)
