AnnotationManager::getAnnotationsInBounds broken

[incanus]

Noticed while working in #1655 — applies to current master as well. Always comes up empty.

[1ec5]

Reproduces until you zoom in or out.

Not sure what conditions you were seeing this under @1ec5, but my case was due to not clamping latitude for Mercator (bf6be3c) and another issue around returning duplicate annotations for the query (8626f91).

This is all patched up now. 376ad5e fixes things for shapes (union, not containment) and da01318 allows filtering by annotation type in the C++ API, which iOS now uses to filter to just points for tap selection.

I was seeing #1675 rather than this bug.
