From: Nelson Castillo <[email protected]> We were waiting 60ms before reporting a pen-up event to avoid jitter. Now we wait 8ms (actually 5 with HZ == 200).
Thanks to Marco Trevisan for testing and pointing out that there was a problem that could be spotted with the illume keyboard. Note that I used the Terminal mode of the keyboard (no dictionary) for tests. I also used touch_test.py and the jitter doesn't seem to be an issue when drawing lines with the finger.
