Details
I think we don't have a hit testing cache, yet hit testing can take occasionally some time. If nothing has changed in layout and events requiring hit testing happen close each others, like with mousemove, we should be able the return the result of the previous hittest quite often.

Now that we have retained display lists, we could try using that for hit testing.
