Title: double tap passthrough

This eliminates some redundant code when passing along annotation double-taps to the underlying tiled layer. This simplifies the addition of [this feature](https://github.com/Alpstein/route-me/issues/59#issuecomment-6099596) since both types of double-taps need to be recognized and evaluated in that case, and performing the `center` check code in two places is undesirable.
