/*
* @note Scrolling by `:pixel` may not actually be by real pixels, but instead
* correspond to Cocoa co-ords (I don't have a retina display, so I
* haven't checked it out yet).
*
* Generate `amount` scroll events at the current cursor position
*
* Returns number of lines/pixels scrolled, default `units` are by `line`.
* A positive `amount` will scroll up and a negative `amount` will scroll down.
*
* An animation duration can also be specified, which defaults to 0.2 seconds.
*
* @overload scroll(amount)
* @param amount [Number]
* @return [Number]
* @overload scroll(amount, units)
* @param amount [Number]
* @param units [Symbol] `:pixel` or `:line`
* @return [Number]
* @overload scroll(amount, units, duration)
* @param amount [Number]
* @param units [Symbol] `:pixel` or `:line`
* @param duration [Number] animation time, in seconds
* @return [Number]
