Handler
Handlers interpret dom events and return camera changes that should be
applied to the map (HandlerResults). The camera changes are all deltas.
The handler itself should have no knowledge of the map's current state.
This makes it easier to merge multiple results and keeps handlers simpler.
For example, if there is a mousedown and mousemove, the mousePan handler
would return a panDelta on the mousemove.
Methods
