Description

I'm building a touch-enabled list, and basically have to replace a scroller with my own logic to scroll the list and select items.

To my surprise, dataGroup does not have a maximum scroll position. This is confusing to developers, as we expect this property. Supposedly, the way to get the value is to use dataGroup.contentWidth - viewportWidth. I assume there is some complexity that makes this more complicated, but if its this straightforward, why not add the properties?
