It's the same as sliding with the one finger from right to middle. Remember
the pressure is also important for the "average", so if you hit really hard
with the left finger, the "avg" still does no "jump" but a fast move over the
middle some way left and then back to middle. still a single point gesture.
Allegedly there is (or has been) sth like "pressure detection" in the
ts-driver, that probably meassures the R *between* the 2 foils. IIRC that
couldn't be done with GTA01, but is maybe feasible with GTA02. It would give
some additional info to maybe distinguish multitouch from gesture. I already
said I'll have a look at it some day...
