SmallTouchFilter default 20 pixels?

[Johan Vos]

The Monocle Touch handling will by default add a SmallMoveTouchFilter (see
TouchInput:75), and this SmallMoveTouchFilter will by default block touch
events if the touch event is within a radius of 20 pixels from the previous
one.

Both the addition of SmallMoveTouchFilter as well as the radius of the
SmallMoveTouchFilter can easily be configured using system properties, but
it sounds strange to me that the default will ignore touch events that are
less than 20 pixels apart? On Android, we have to set the default to 1
pixel in order to get responsive applications.
