Added <sequence> for playing movie outputs and other sequences
of related results.
Added <resize> option to <image> elements. This can be used to
resize input items to a smaller size, so they don't take up so
much real estate on the form.
Fixed a bug in right/below cases for popup balloons.
Reduced the tooltip delay time to 750ms to interact better with
Rick's attention span.
Fixed the sash between grips to light up when you touch it, so
it's easier to see.
