Code review comment for lp:~oif-team/grail/trunk.fixes

Test results:

1. Regression: If you use a physical trackpad button to click while there's no movement on the trackpad, it's held up until a movement is performed.

2. Timeouts seem ok. I was able to request all 3, 4, and 5 finger gestures and still perform two finger multitouch reasonably. I will perform more thorough testing when the regressions are resolved.

3. Regression: I often get a tap event at the end of a drag gesture sequence. The tap touch count matches the drag touch count.
