ImmediateInterpreter: properly scroll, point

This fixes 2 bugs that were found with the activity log/replay
(yay!). We need to increase the pressure difference threshold between
thumb and finger, as two fingers were accidentally being classified as
a finger + thumb.

Also, due to a mistaken dy computation, we were failing to classify
fingers as resting thumbs that were in the bottom zone.

BUG=chromium-os:21735
TEST=unittest; tested on device
