Subject: [PATCH 8/8] Send pen-up events faster (side effect: improve illume keyboard responsiveness)
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit
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.
