/**
* Ticker that scrolls its contents with various speeds and pauses
*
* @param $fields
* An associative array of fields, possibly including:
*
* "content_fbml" => string
* The FBML content of the ticker. The first top-level element
* should contain sub-elements, and their sizes determine where
* the ticker would pause between automatically scrolling.
* The ticker animates by scrolling its inner contents.
*
* "vertical" => bool
* Defaults to true. If false, the ticker scrolls horizontally.
*
* "speed" => bool
* The scrolling speed.
* This is the number of items that would scroll by in 1 second,
* if there were no pauses.
* When the speed is positive, vertical tickers scroll down, and
* horizontal tickers scroll to the right. New content seems to come in
* from the bottom (for vertical tickers) or right (for horizontal tickers)
* as the ticker scrolls. The element inside the ticker will start out
* aligned with the top side of the ticker (for vertical tickers),
* or the left side of the ticker (for horizontal tickers).
* When the speed is negative, all this faces the other way.
*
* "pause_ms" => int
* Defaults to 2000. This is the number of milliseconds to wait
* after each second-level element of $content_fbml is automatically
* scrolled completely into view.
*
* "pause_ms_min" => int
* If set, then the number of milliseconds to pause is a random
* integer between $pause_ms_min and $pause_ms.
*
* "scrollbars" => bool
* Defaults to true. If true, shows scrollbars, otherwise doesn't.
* (Note: this will let the user know how much content is left,
* and be able to see it before it would automatically scroll into view.)
*
* "scrollbars_pause_ms" => int
* Defaults to 500. The ticker pauses its automatic scrolling when the user
* starts using the scrollbars. This is the number of milliseconds to wait
* until resuming the automatic scrolling.
*
* "anim_ms" => int
* Defaults to 100. This is the number of milliseconds between calls to
* autoScroll.
*
* "initial_scroll_mode" => int
* Defaults to 'auto'. This is the mode that scrolling starts out in.
* Possible values are 'auto' and 'paused'.
*
* "ease" => string
* Optional. If set, specifies the name of the ease function
