/*
* FormData for XMLHttpRequest 2 - Polyfill for Web Worker
* (c) 2014 Rob Wu <rob@robwu.nl>
* License: MIT
* - append(name, value[, filename])
* - XMLHttpRequest.prototype.send(object FormData)
*
* Specification: http://www.w3.org/TR/XMLHttpRequest/#formdata
* http://www.w3.org/TR/XMLHttpRequest/#the-send-method
* The .append() implementation also accepts Uint8Array and ArrayBuffer objects
* Web Workers do not natively support FormData:
* http://dev.w3.org/html5/workers/#apis-available-to-workers
* Originally released in 2012 as a part of http://stackoverflow.com/a/10002486.
* Updates since initial release:
* - Forward-compatibility by testing whether FormData exists before defining it.
* - Increased robustness of .append.
* - Allow any typed array in .append.
* - Remove use of String.prototype.toString to work around a Firefox bug.
* - Use typed array in xhr.send instead of arraybuffer to get rid of deprecation
* warnings.
