Yeah, this fixes the annoying issue with multiple fingers.

Now only the problem with the wrong axis ranges is remaining.

I've tried with my version of the hardware (a old v2) and it doesn't 
seem to have the problem you describe.

Basically your problem is that the driver reports ranges as 0-1152 and 
0-576, but in reality, when you move your finger, the coordinates stay 
in the ranges 0-819, 171-576. So in practice the cursor moves as 
expected but the borders to allow the scrolling don't work. Is that right?

I wonder if it's normal that the device has a range even smaller than 
what it reports, and whether something can be done. JJ Ding?

I asked our firmware team and windows team, the v2 hardware is such a
wild beast. ;-) It has many variants WRT x, y ranges (due to different
scanning methods the hardware is using.) I am preparing a patch that
will hopefully fix this issue for all the v2 variants.
