The test failures occurred in the "fingerprinting resistance off" case.
Kathy came up with a good theory: maybe the doubling of the radius
occurred because I ran the tests on a Mac with a Retina (2x) display. If
that is what is happening, this seems like a Firefox bug (maybe in the
test code that synthesizes events?) since all distance units within the
Touch Events are supposed to be CSS pixels. This should not prevent us
from merging these patches.
