Is a cache for a given element's scroll information (all the info that ScrollController stores)
in addition the "client rectangle" of the element.. the area within the scrollbars.
The cache can be in one of two modes:
- doesListening:false - ignores when the container is scrolled by someone else
- doesListening:true - watch for scrolling and update the cache
