Tapping point annotation does not select it at z0

[1ec5]

Tapping a point annotation on iOS does not select it when the map is at zoom level 0.

Interesting. Previously, we've had render issues in that department (#1279) and also, I would have suspected something in the original memory tile-based storage of points, but @jfirebaugh has refactored that into an R-tree recently (#2673). I don't have much more to provide other than that context, though.

Globally tapping annotation should not only suppose user tapped near the annotation's coordinate. As with annotationImage offset, it should take it into account too.
Internal code should be reworked for that.

This is fixed in the OS X port. Backporting to iOS is blocked on #3159.

This will be fixed in #3261.
