Tap on Map to Mark Cameras

[milo-trujillo]

It is not always feasible to stand right below a camera when marking it, or GPS may be too inaccurate to show you under the camera. We should be able to tap on a map location nearby to mark a camera at that position.

There are already several map gestures we do not want to disrupt with this feature:

• Tapping a pin to select it and get more information
• Double tapping the map to zoom in
• Two finger scrolling
• Three finger tilting

Therefore, the new gesture should only trigger if none of the others are applicable. In addition, users should only be able to add a camera within some radius of their GPS position. This means users can mark cameras in their vicinity when GPS is insufficiently accurate, but can't scroll over to another continent and start tapping out cameras to troll other users.
