Christian Robertson 4b65f0ebee Tunings for touch ripple animations
Added a log based interpolator (it's faster in the beginning and smoother
at the finish than the decelerate interpolator)

Scaled the timing and opacity of the falloff ripple based on the size
of the outer bounding radius. Backing circles aren't as apparent for
Smaller touch targets.
