OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

Problem During Load because of wrong ss:ExpandedRowCount.

	* draw a multiline string rotated in a canvas
	*
	* @param ctx (M) context of the canvas
	* @param text (M) string may contain \n
	* @param posX (M) horizontal start position

	* Why CLOSURES are great!
	*
	* Think of Closures as Functions within Functions... where nested functions have access to parent function variables
	* and arguments. So, you may ask?
	*
	* Closures allow developers to temporarily cache data!
	* Closures can simplify recursion or iterations (aka visitors pattern)
	* Closures can solve real-world `callback` problems; especially powerful for asynchronous callbacks.

	public class Something
	{
	public function doSomething(index:int) : void
	{
	// Async closure for timer completion event
	function onComplete_doSomething(evt:TimerEvent) : void
	{
	// Always clean up 1st, then notify listeners
	timer.removeEventListener(TimerEvent.TIMER, onComplete_Timer );

	// Example usage:
	//
	// int[] numbers = {1, 2, 3, 4, 5, 6, 7};
	// int[][] chunks = chunkArray(numbers, 3);
	//
	// chunks now contains [
	// [1, 2, 3],
	// [4, 5, 6],
	// [7]
	// ]
