// ## Usage

// To use this plugin, you simply add an `iframe` option with the value `true`
// to the Ajax settings an `$.ajax()` call, and specify the file fields to
// include in the submssion using the `files` option, which can be a selector,
// jQuery object, or a list of DOM elements containing one or more
// `<input type="file">` elements:

//     $("#myform").submit(function() {
//         $.ajax(this.action, {
//             files: $(":file", this),
//             iframe: true
//         }).complete(function(data) {
//             console.log(data);
//         });
//     });

// The plugin will construct hidden `<iframe>` and `<form>` elements, add the
// file field(s) to that form, submit the form, and process the response.

// If you want to include other form fields in the form submission, include
// them in the `data` option, and set the `processData` option to `false`:

//     $("#myform").submit(function() {
//         $.ajax(this.action, {
//             data: $(":text", this).serializeArray(),
//             files: $(":file", this),
//             iframe: true,
//             processData: false
//         }).complete(function(data) {
//             console.log(data);
//         });
//     });

// ### Response Data Types

// As the transport does not have access to the HTTP headers of the server
// response, it is not as simple to make use of the automatic content type
// detection provided by jQuery as with regular XHR. If you can't set the
// expected response data type (for example because it may vary depending on
// the outcome of processing by the server), you will need to employ a
// workaround on the server side: Send back an HTML document containing just a
// `<textarea>` element with a `data-type` attribute that specifies the MIME
// type, and put the actual payload in the textarea:

//     <textarea data-type="application/json">
//       {"ok": true, "message": "Thanks so much"}
//     </textarea>

// The iframe transport plugin will detect this and pass the value of the
// `data-type` attribute on to jQuery as if it was the "Content-Type" response
// header, thereby enabling the same kind of conversions that jQuery applies
// to regular responses. For the example above you should get a Javascript
// object as the `data` parameter of the `complete` callback, with the
// properties `ok: true` and `message: "Thanks so much"`.

// ### Handling Server Errors

// Another problem with using an `iframe` for file uploads is that it is
// impossible for the javascript code to determine the HTTP status code of the
// servers response. Effectively, all of the calls you make will look like they
// are getting successful responses, and thus invoke the `done()` or
// `complete()` callbacks. You can only communicate problems using the content
// of the response payload. For example, consider using a JSON response such as
// the following to indicate a problem with an uploaded file:

//     <textarea data-type="application/json">
//       {"ok": false, "message": "Please only upload reasonably sized files."}
//     </textarea>

// ### Compatibility

// This plugin has primarily been tested on Safari 5 (or later), Firefox 4 (or
// later), and Internet Explorer (all the way back to version 6). While I
// haven't found any issues with it so far, I'm fairly sure it still doesn't
// work around all the quirks in all different browsers. But the code is still
// pretty simple overall, so you should be able to fix it and contribute a
// patch :)

		 *
		 * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
		 *
		 * Solution:
		 *
		 * We assume the radius of the polygon is half the size of the canvas at first
		 * at each index we check if the text overlaps.
		 *
		 * Where it does, we store that angle and that index.
		 *
		 * After finding the largest index and angle we calculate how much we need to remove
		 * from the shape radius to move the point inwards by that x.
		 *
		 * We average the left and right distances to get the maximum shape radius that can fit in the box
		 * along with labels.
		 *
		 * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
		 * on each side, removing that from the size, halving it and adding the left x protrusion width.
		 *
		 * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
		 * and position it in the most space efficient manner
