Certain assistive technologies (like HoverText) send very rapid hit-tests that are all close to each other (think of a mouse moving across the screen). Use this knowledge to build an optimization where when we get a hit-test from an AT, we asynchronously also hit test nearby points and cache the results, meaning we can instantly serve follow-up AT hit-tests for nearby points.
