Lat/Long 0,0 -- Actions vs. Maps

I’ve noted that various of the docs say that a lat/long of 0,0 means “no change in position” – though MP and QGC both show thousands of miles offsets on their maps. But testing 0,0 (e.g., for loiter circle) in SITL shows that indeed ArduCopter treats 0,0 as staying in the current position. Interesting difference of opinion!
