Revert "Filter out events jittery for single-touch gestures."

This reverts commit f7f8b960f56cbd66560b7590e24983beb9e63509.

The reverted commit was removing the events which are required for
smoothness. The gesture_detector.cc module handles extra events
received. We just need to pass them to it.

This is a port of the following patch:
