Comment (by mcs):

 I reviewed the patches and they look okay. But for some reason when I run
 the tests on OSX two of them fail:
 {{{
 6 INFO TEST-UNEXPECTED-FAIL |
 dom/events/test/test_touchevent_resist_fingerprinting.html | touch.radiusX
 - got 4, expected 2
 7 INFO TEST-UNEXPECTED-FAIL |
 dom/events/test/test_touchevent_resist_fingerprinting.html | touch.radiusY
 - got 6, expected 3
 }}}
 I am not yet sure why the failures are occuring. Unfortunately I am out of
 time for now, but I will try to investigate more later tonight or early
 tomorrow.
