The animation service now keeps track of the active animation frame request and will skip new requests until the current one is executed. This can happen when processing mouse events, e.g. 'mousemove' and 'mouseout' events will trigger multiple renders.
Usage: `.update(animationDuration, [bool])`
Tooltip animations are now "lazy” by default, meaning they can be
interrupted and pivoted by other animations. All others internal
updates are by nature non-interruptible, so hovering over a chart
during a regular `update()` cycle will pivot the tooltip correctly.
