/**
Workaround for iOS 6 setTimeout bug using requestAnimationFrame to simulate timers during Touch/Gesture-based events
Author: Jack Pattishall (jpattishall@gmail.com)
This code is free to use anywhere (MIT, etc.)

Note: UIWebView does not support requestAnimationFrames. If your timer is failing during a scroll event,
take a look at https://gist.github.com/ronkorving/3755461 for a potential workaround.

Usage: Pass TRUE as the final argument for setTimeout or setInterval.

	// This library re-implements setTimeout, setInterval, clearTimeout, clearInterval for iOS6.
	// iOS6 suffers from a bug that kills timers that are created while a page is scrolling.
	// This library fixes that problem by recreating timers after scrolling finishes (with interval correction).
	// This code is free to use by anyone (MIT, blabla).
	// Original Author: rkorving@wizcorp.jp
	var timeouts = {};
	var intervals = {};
	var orgSetTimeout = window.setTimeout;
	var orgSetInterval = window.setInterval;

	Create a fixed number of instances of a class.
	Use "lazy instantiation" to create objects only if needed.
	If the maximum number of instances has been reached, return a random one from the ones created.

Update 2022: git checkout -p <other-branch> is basically a shortcut for all this.

FYI This was written in 2010, though I guess people still find it useful at least as of 2021. I haven't had to do it ever again, so if it goes out of date I probably won't know.

Example: You have a branch refactor that is quite different from master. You can't merge all of the commits, or even every hunk in any single commit or master will break, but you have made a lot of improvements there that you would like to bring over to master.

Note: This will not preserve the original change authors. Only use if necessary, or if you don't mind losing that information, or if you are only merging your own work.
