Better Scrolling Performance [Web]

Perceived scroll performance has been dramatically improved in this release. This applies to Views that use displayRectChanged events to update themselves. List and many other controls do this to support extremely large collections. They store only what is needed to render the current viewport. The drawback to this before, was that a user could see the gaps while scrolling very quickly.

This has now been fixed, so these views appear without any tearing as the user scrolls.

As a result, List and similar collection controls default to caching 0 items outside the viewport. This was some non-zero value before
to provide some buffer for scroll tearing.
