Ability to use the Measure control with a point handler

[fvanderbiest]

Currently, getBestArea is called even if we use the Measure control with a point handler. This does not make sense. A patch is attached.

map.getUnits() should be used in place of map.units.

openlayers_2511_A1.diff makes use of displayProjection should the user wants a specific projection for the position value, modifies the API doc strings as needed, modifies the measure.html example to demonstrate the new feature, and provides unit tests for the measure function. The tests pass in IE8, FF3 and Chromium 5. The measure.html works in these browsers.

fvanderbiest, tell me if this new patch works for you. I'll wait for a few days before committing this patch, in case someone else would like to review it.

Thanks fvanderbiest for the initial patch.

Patch A1 works great. Thanks for the added value, Eric.

It strikes me as a little odd that a point could be measured (the MousePosition control seems more appropriate for this), but I don't want to keep this out if others find it sensible.

And, I assume (but haven't verified) that the displayProjection option plays well with the geodesic option.

Replying to tschaub:

I see your point Tim, but the mousePosition control does not enable drawing of a vector feature, nor is it possible to freeze the measurement at some point. In our case, having a point feature drawn on click is useful, because it enables the user to see where the position measurement was taken.

This one can be bumped to 2.10 from my perspective.

We decided to go another path. Closing as wontfix.
