1.3: Improve fling scroll performance

Using my MacBook trackpad, opening a file in moar, fling scrolling now feels
like it does in any other non-console app. Before this release it was slow, and
kept scrolling long after it should have stopped.

Most other changes in this release are internal.

right.
