I think the *maximum* scroll velocity value should be increased from
current -  if you do a fast/long swipe gesture, the scroll speed should be
faster than it currently is. Compare the scrolling speed of a listview on a
quick swipe on Android to ours, and you see what I mean.

There was a bug raised for this that seemed to link this issue to the max
velocity being defined in pixels instead of a resolution independent unit -
not sure if MP was ever approved?

I am not sure what the max value should be, but I feel the max speed should
be at least double what it currently is.

Florian?
