This resolves an issue in eraser-map where the user's current location is not visible in a (tilted) routing view. \r\n\r\nWhile making these changes, I found a subtle but important issue related to input handling: \r\n\r\n`InputHandler` sets a fling delta every time that a pan above some threshold occurs. On any frame in which `handlePanGesture` isn't called, that delta is repeatedly applied and decremented to give a smooth fling. The problem is that while a finger/mouse is down and moving, *input events may not occur on every frame*. This results in a panning motion from both the fling delta and (later) the input callback, causing a translational drift. Fixing this with our existing input callbacks seems difficult - the information we really need is touch-up and touch-down events.\r\n\r\nSince this issue may require API revision and isn't terribly problematic for most use cases, I've elected to leave it unresolved for now.
