scroller iPhone with bounce

[BNig]

I figured the scroller example in Livecode mobile 4.5.2 was not really
complete so I set up the new scroller in a little stack: a list field with a
bounce. The bounce was not obvious from the example so I hope this helps
people to implement this. (look at the group "umscroll" with lockloc true
and the list field)
Almost all the code is in the card script. Except for a mouseUp handler in
the list field to make the actual selection.

The new scroller is a very nice object that really makes things a lot
easier. It scrolls very smoothly even on my slow iPhone 3G. Selection is a
lot easier since the operating system takes a lot of guesswork out of when a
touch is the begin of a scroll and when a touch is a selection.

There is one quirk in the current incarnation of the mobile engine:
the scroll is really only starting to scroll if you slide the field up and
then touch the network bar or whatever you call it. The top line of the
screen where the battery is shown etc. This 'defrosts' the scrolling and
from then on you can scroll and bounce like you expect it. Runrev is aware
of the problem.

the zipped version of the stack:
