The appletouch driver is prone to reporting multiple fingers when
only
one is
pressing.  The appletouch driver queries an array of pressure sensors
and
counts local maxima in pressure to determine the number of
fingers.  It
just
does this on the raw values, so a data stream like:

0 100 250 300 299 300 250 100 0

actually registers as 2 fingers.

This patch updates the logic to ignore small dips in pressure that
are
less
than the threshold.
Does it still detect 2 fingers as 2 fingers when they are held
together?
I just wanted to follow up on this patch[1], since I haven't seen any
movement.  It's fairly trivial and I've been using it for the past
month with great success (yes, it still detects 2 fingers properly).
Is there hope that this change can get merged soon?
Gah, I was sure I applied it to 'next'. Sorry about that, I will
make sure it gets into .31.
