-/*! p5.dom.js v0.3.4 Aug 11, 2017 */
-/**
- * <p>The web is much more than just canvas and p5.dom makes it easy to interact
- * with other HTML5 objects, including text, hyperlink, image, input, video,
- * audio, and webcam.</p>
- * <p>There is a set of creation methods, DOM manipulation methods, and
- * an extended p5.Element that supports a range of HTML elements. See the
- * <a href="https://github.com/processing/p5.js/wiki/Beyond-the-canvas">
- * beyond the canvas tutorial</a> for a full overview of how this addon works.
- *
- * <p>Methods and properties shown in black are part of the p5.js core, items in
- * blue are part of the p5.dom library. You will need to include an extra file
- * in order to access the blue functions. See the
- * <a href="http://p5js.org/libraries/#using-a-library">using a library</a>
- * section for information on how to include this library. p5.dom comes with
- * <a href="http://p5js.org/download">p5 complete</a> or you can download the single file
- * <a href="https://raw.githubusercontent.com/lmccart/p5.js/master/lib/addons/p5.dom.js">
- * here</a>.</p>
- * <p>See <a href="https://github.com/processing/p5.js/wiki/Beyond-the-canvas">tutorial: beyond the canvas</a>

This array is the size (include an appropriate\nfactor for pixelDensity) of the display window x4,\nrepresenting the R, G, B, A values in order for each pixel, moving from\nleft to right across each row, then down each column. Retina and other\nhigh density displays will have more pixels[] (by a factor of\npixelDensity^2).\nFor example, if the image is 100x100 pixels, there will be 40,000. On a\nretina display, there will be 160,000.\n<br><br>\nThe first four values (indices 0-3) in the array will be the R, G, B, A\nvalues of the pixel at (0, 0). The second four values (indices 4-7) will\ncontain the R, G, B, A values of the pixel at (1, 0). More generally, to\nset values for a pixel at (x, y):</p>\n<pre><code class=\"lang-javascript\">var d = pixelDensity();\nfor (var i = 0; i &lt; d; i++) {\n  for (var j = 0; j &lt; d; j++) {\n    // loop over\n    idx = 4 * ((y * d + j) * width * d + (x * d + i));\n    pixels[idx] = r;\n    pixels[idx+1] = g;\n    pixels[idx+2] = b;\n    pixels[idx+3] = a;\n  }\n}\n</code></pre>\n<p>While the above method is complex, it is flexible enough to work with\nany pixelDensity. Note that set() will automatically take care of\nsetting all the appropriate values in pixels[] for a given (x, y) at\nany pixelDensity, but the performance may not be as fast when lots of\nmodifications are made to the pixel array.\n<br><br>\nBefore accessing this array, the data must loaded with the loadPixels()\nfunction. After the array data has been modified, the updatePixels()\nfunction must be run to update the changes.\n<br><br>\nNote that this is not a standard javascript array.

Perlin noise is\na random sequence generator producing a more natural ordered, harmonic\nsuccession of numbers compared to the standard <b>random()</b> function.\nIt was invented by Ken Perlin in the 1980s and been used since in\ngraphical applications to produce procedural textures, natural motion,\nshapes, terrains etc.<br /><br /> The main difference to the\n<b>random()</b> function is that Perlin noise is defined in an infinite\nn-dimensional space where each pair of coordinates corresponds to a\nfixed semi-random value (fixed only for the lifespan of the program; see\nthe noiseSeed() function). p5.js can compute 1D, 2D and 3D noise,\ndepending on the number of coordinates given. The resulting value will\nalways be between 0.0 and 1.0. The noise value can be animated by moving\nthrough the noise space as demonstrated in the example above. The 2nd\nand 3rd dimension can also be interpreted as time.<br /><br />The actual\nnoise is structured similar to an audio signal, in respect to the\nfunction&#39;s use of frequencies. Similar to the concept of harmonics in\nphysics, perlin noise is computed over several octaves which are added\ntogether for the final result. <br /><br />Another way to adjust the\ncharacter of the resulting sequence is the scale of the input\ncoordinates. As the function works within an infinite space the value of\nthe coordinates doesn&#39;t matter as such, only the distance between\nsuccessive coordinates does (eg. when using <b>noise()</b> within a\nloop). As a general rule the smaller the difference between coordinates,\nthe smoother the resulting noise sequence will be. Steps of 0.005-0.03\nwork best for most applications, but this will differ depending on use.</p>\n",

-/**
-  `Promise.all` accepts an array of promises, and returns a new promise which
-  is fulfilled with an array of fulfillment values for the passed promises, or
-  rejected with the reason of the first passed promise to be rejected. It casts all
-  elements of the passed iterable to promises as it runs this algorithm.
-
-  Example:
-
-  ```javascript
-  let promise1 = resolve(1);
-  let promise2 = resolve(2);
-  let promise3 = resolve(3);
-  let promises = [ promise1, promise2, promise3 ];
-
-  Promise.all(promises).then(function(array){
-    // The array here would be [ 1, 2, 3 ];
-  });
-  ```
-
-  If any of the `promises` given to `all` are rejected, the first promise
-  that is rejected will be given as an argument to the returned promises's
-  rejection handler. For example:
-
-  Example:
-
-  ```javascript
-  let promise1 = resolve(1);
-  let promise2 = reject(new Error("2"));
-  let promise3 = reject(new Error("3"));
-  let promises = [ promise1, promise2, promise3 ];
-
-  Promise.all(promises).then(function(array){
-    // Code here never runs because there are rejected promises!
-  }, function(error) {
-    // error.message === "2"
-  });
-  ```
-
-  @method all
-  @static
-  @param {Array} entries array of promises
-  @param {String} label optional string for labeling the promise.

-/**
-  Promise objects represent the eventual result of an asynchronous operation. The
-  primary way of interacting with a promise is through its `then` method, which
-  registers callbacks to receive either a promise's eventual value or the reason
-  why the promise cannot be fulfilled.
-
-  Terminology
-  -----------
-
-  - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
-  - `thenable` is an object or function that defines a `then` method.
-  - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
-  - `exception` is a value that is thrown using the throw statement.
-  - `reason` is a value that indicates why a promise was rejected.
-  - `settled` the final resting state of a promise, fulfilled or rejected.
-
-  A promise can be in one of three states: pending, fulfilled, or rejected.
-
-  Promises that are fulfilled have a fulfillment value and are in the fulfilled
-  state.  Promises that are rejected have a rejection reason and are in the
-  rejected state.  A fulfillment value is never a thenable.
-
-  Promises can also be said to *resolve* a value.  If this value is also a
-  promise, then the original promise's settled state will match the value's
-  settled state.  So a promise that *resolves* a promise that rejects will
-  itself reject, and a promise that *resolves* a promise that fulfills will
-  itself fulfill.
-
-
-  Basic Usage:
-  ------------
-
-  ```js
-  let promise = new Promise(function(resolve, reject) {
-    // on success
-    resolve(value);
-
-    // on failure
-    reject(reason);
-  });
-
-  promise.then(function(value) {
-    // on fulfillment
-  }, function(reason) {
-    // on rejection
-  });
-  ```
-
-  Advanced Usage:
-  ---------------
-
-  Promises shine when abstracting away asynchronous interactions such as
-  `XMLHttpRequest`s.
-
-  ```js
-  function getJSON(url) {
-    return new Promise(function(resolve, reject){
-      let xhr = new XMLHttpRequest();
-
-      xhr.open('GET', url);
-      xhr.onreadystatechange = handler;
-      xhr.responseType = 'json';
-      xhr.setRequestHeader('Accept', 'application/json');
-      xhr.send();
-
-      function handler() {
-        if (this.readyState === this.DONE) {
-          if (this.status === 200) {
-            resolve(this.response);
-          } else {
-            reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
-          }
-        }
-      };
-    });
-  }
-
-  getJSON('/posts.json').then(function(json) {
-    // on fulfillment
-  }, function(reason) {
-    // on rejection
-  });
-  ```
-
-  Unlike callbacks, promises are great composable primitives.
-
-  ```js
-  Promise.all([
-    getJSON('/posts'),
-    getJSON('/comments')
-  ]).then(function(values){
-    values[0] // => postsJSON
-    values[1] // => commentsJSON
-
-    return values;
-  });
-  ```

-    this instanceof Promise ? initializePromise(this, resolver) : needsNew();

-  /**
-    The primary way of interacting with a promise is through its `then` method,
-    which registers callbacks to receive either a promise's eventual value or the
-    reason why the promise cannot be fulfilled.
-  
-    ```js

-      // user is available
-    }, function(reason){
-      // user is unavailable, and you are given the reason why
-    });
-    ```
-  
-    Chaining
-    --------
-  
-    The return value of `then` is itself a promise.  This second, 'downstream'
-    promise is resolved with the return value of the first promise's fulfillment
-    or rejection handler, or rejected if the handler throws an exception.
-  
-    ```js
-    findUser().then(function (user) {
-      return user.name;
-    }, function (reason) {
-      return 'default name';
-    }).then(function (userName) {
-      // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
-      // will be `'default name'`
-    });
-  
-    findUser().then(function (user) {
-      throw new Error('Found user, but still unhappy');
-    }, function (reason) {
-      throw new Error('`findUser` rejected and we're unhappy');
-    }).then(function (value) {
-      // never reached
-    }, function (reason) {
-      // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
-      // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
-    });
-    ```
-    If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
-  
-    ```js
-    findUser().then(function (user) {
-      throw new PedagogicalException('Upstream error');
-    }).then(function (value) {
-      // never reached
-    }).then(function (value) {
-      // never reached
-    }, function (reason) {
-      // The `PedgagocialException` is propagated all the way down to here
-    });
-    ```
-  
-    Assimilation
-    ------------
-  
-    Sometimes the value you want to propagate to a downstream promise can only be
-    retrieved asynchronously. This can be achieved by returning a promise in the
-    fulfillment or rejection handler. The downstream promise will then be pending
-    until the returned promise is settled. This is called *assimilation*.
-  
-    ```js
-    findUser().then(function (user) {
-      return findCommentsByAuthor(user);
-    }).then(function (comments) {
-      // The user's comments are now available
-    });
-    ```
-  
-    If the assimliated promise rejects, then the downstream promise will also reject.
-  
-    ```js
-    findUser().then(function (user) {
-      return findCommentsByAuthor(user);
-    }).then(function (comments) {
-      // If `findCommentsByAuthor` fulfills, we'll have the value here
-    }, function (reason) {
-      // If `findCommentsByAuthor` rejects, we'll have the reason here
-    });
-    ```
-  
-    Simple Example

-  
-    Synchronous Example
-  
-    ```javascript
-    let result;
-  
-    try {
-      result = findResult();

-* (c) 2017 Axel Kittenberger
-*
-* This interpreter has been implemented according to this documentation:
-* https://developer.apple.com/fonts/TrueType-Reference-Manual/RM05/Chap5.html
-*
-* According to the documentation F24DOT6 values are used for pixels.
-* That means calculation is 1/64 pixel accurate and uses integer operations.
-* However, Javascript has floating point operations by default and only
-* those are available. One could make a case to simulate the 1/64 accuracy
-* exactly by truncating after every division operation
-* (for example with << 0) to get pixel exacty results as other TrueType
-* implementations. It may make sense since some fonts are pixel optimized
-* by hand using DELTAP instructions. The current implementation doesn't
-* and rather uses full floating point precission.
-*
-* xScale, yScale and rotation is currently ignored.
-*
-* A few non-trivial instructions are missing as I didn't encounter yet
-* a font that used them to test a possible implementation.
-*
-* Some fonts seem to use undocumented features regarding the twilight zone.
-* Only some of them are implemented as they were encountered.
-*
-* The DEBUG statements can be removed, manually or for example with "uglify"
-* fixing DEBUG to false.

-INTERPOLATE:
-============
-
-Examples of point interpolation.
-
-The weight of the movement of the reference point gets bigger
-the further the other reference point is away, thus the safest
-option (that is avoiding 0/0 divisions) is to weight the
-original distance of the other point by the sum of both distances.
-
-If the sum of both distances is 0, then move the point by the
-arithmetic average of the movement of both refererence points.

-   * Called directly before setup(), the preload() function is used to handle
-   * asynchronous loading of external files. If a preload function is
-   * defined, setup() will wait until any load calls within have finished.
-   * Nothing besides load calls should be inside preload (loadImage,
-   * loadJSON, loadFont, loadStrings, etc).<br><br>
-   * By default the text "loading..." will be displayed. To make your own
-   * loading page, include an HTML element with id "p5_loading" in your
-   * page. More information <a href="http://bit.ly/2kQ6Nio">here</a>.
-   *
-   * @method preload
-   * @example
-   * <div><code>
-   * var img;
-   * var c;
-   * function preload() {  // preload() runs once
-   *   img = loadImage('assets/laDefense.jpg');
-   * }
-   *
-   * function setup() {  // setup() waits until preload() is done
-   *   img.loadPixels();
-   *   // get color of middle pixel
-   *   c = img.get(img.width/2, img.height/2);
-   * }
-   *
-   * function draw() {

-  /**
-   * The setup() function is called once when the program starts. It's used to
-   * define initial environment properties such as screen size and background
-   * color and to load media such as images and fonts as the program starts.
-   * There can only be one setup() function for each program and it shouldn't
-   * be called again after its initial execution.
-   * <br><br>
-   * Note: Variables declared within setup() are not accessible within other
-   * functions, including draw().
-   *
-   * @method setup
-   * @example
-   * <div><code>
-   * var a = 0;
-   *
-   * function setup() {
-   *   background(0);
-   *   noStroke();
-   *   fill(102);
-   * }
-   *

-  /**
-   * Called directly after setup(), the draw() function continuously executes
-   * the lines of code contained inside its block until the program is stopped
-   * or noLoop() is called. Note if noLoop() is called in setup(), draw() will
-   * still be executed once before stopping. draw() is called automatically and
-   * should never be called explicitly.
-   * <br><br>
-   * It should always be controlled with noLoop(), redraw() and loop(). After
-   * noLoop() stops the code in draw() from executing, redraw() causes the
-   * code inside draw() to execute once, and loop() will cause the code
-   * inside draw() to resume executing continuously.
-   * <br><br>
-   * The number of times draw() executes in each second may be controlled with
-   * the frameRate() function.
-   * <br><br>
-   * There can only be one draw() function for each sketch, and draw() must
-   * exist if you want the code to run continuously, or to process events such
-   * as mousePressed(). Sometimes, you might have an empty call to draw() in
-   * your program, as shown in the above example.
-   * <br><br>
-   * It is important to note that the drawing coordinate system will be reset
-   * at the beginning of each draw() call. If any transformations are performed
-   * within draw() (ex: scale, rotate, translate, their effects will be
-   * undone at the beginning of draw(), so transformations will not accumulate
-   * over time. On the other hand, styling applied (ex: fill, stroke, etc) will
-   * remain in effect.
-   *
-   * @method draw
-   * @example
-   * <div><code>
-   * var yPos = 0;
-   * function setup() {  // setup() runs once
-   *   frameRate(30);
-   * }
-   * function draw() {  // draw() loops forever, until stopped
-   *   background(204);
-   *   yPos = yPos - 1;
-   *   if (yPos < 0) {
-   *     yPos = height;
-   *   }
-   *   line(0, yPos, width, yPos);

- * <li><code>DIFFERENCE</code> - subtract colors from underlying image.</li>
- * <li><code>EXCLUSION</code> - similar to <code>DIFFERENCE</code>, but less
- * extreme.</li>
- * <li><code>MULTIPLY</code> - multiply the colors, result will always be

- * <li><code>SCREEN</code> - opposite multiply, uses inverse values of the

- * <li><code>REPLACE</code> - the pixels entirely replace the others and
- * don't utilize alpha (transparency) values.</li>
- * <li><code>OVERLAY</code> - mix of <code>MULTIPLY</code> and <code>SCREEN
- * </code>. Multiplies dark values, and screens light values.</li>
- * <li><code>HARD_LIGHT</code> - <code>SCREEN</code> when greater than 50%
- * gray, <code>MULTIPLY</code> when lower.</li>
- * <li><code>SOFT_LIGHT</code> - mix of <code>DARKEST</code> and
- * <code>LIGHTEST</code>. Works like <code>OVERLAY</code>, but not as harsh.
- * </li>
- * <li><code>DODGE</code> - lightens light tones and increases contrast,

- * The keyPressed() function is called once every time a key is pressed. The

- * <br><br>
- * For non-ASCII keys, use the keyCode variable. You can check if the keyCode
- * equals BACKSPACE, DELETE, ENTER, RETURN, TAB, ESCAPE, SHIFT, CONTROL,
- * OPTION, ALT, UP_ARROW, DOWN_ARROW, LEFT_ARROW, RIGHT_ARROW.
- * <br><br>
- * For ASCII keys that was pressed is stored in the key variable. However, it
- * does not distinguish between uppercase and lowercase. For this reason, it
- * is recommended to use keyTyped() to read the key variable, in which the
- * case of the variable will be distinguished.
- * <br><br>
- * Because of how operating systems handle key repeats, holding down a key
- * may cause multiple calls to keyTyped() (and keyReleased() as well). The
- * rate of repeat is set by the operating system and how each computer is
- * configured.<br><br>

- * /Global_Objects/Uint8ClampedArray' target='_blank'>Uint8ClampedArray</a>
- * containing the values for all the pixels in the display window.
- * These values are numbers. This array is the size (include an appropriate
- * factor for pixelDensity) of the display window x4,
- * representing the R, G, B, A values in order for each pixel, moving from
- * left to right across each row, then down each column. Retina and other
- * high density displays will have more pixels[] (by a factor of
- * pixelDensity^2).
- * For example, if the image is 100x100 pixels, there will be 40,000. On a
- * retina display, there will be 160,000.
- * <br><br>
- * The first four values (indices 0-3) in the array will be the R, G, B, A
- * values of the pixel at (0, 0). The second four values (indices 4-7) will
- * contain the R, G, B, A values of the pixel at (1, 0). More generally, to
- * set values for a pixel at (x, y):
- * ```javascript
- * var d = pixelDensity();
- * for (var i = 0; i < d; i++) {
- *   for (var j = 0; j < d; j++) {
- *     // loop over
- *     idx = 4 * ((y * d + j) * width * d + (x * d + i));
- *     pixels[idx] = r;
- *     pixels[idx+1] = g;
- *     pixels[idx+2] = b;
- *     pixels[idx+3] = a;
- *   }
- * }
- * ```
- * <p>While the above method is complex, it is flexible enough to work with
- * any pixelDensity. Note that set() will automatically take care of
- * setting all the appropriate values in pixels[] for a given (x, y) at
- * any pixelDensity, but the performance may not be as fast when lots of
- * modifications are made to the pixel array.
- * <br><br>
- * Before accessing this array, the data must loaded with the loadPixels()
- * function. After the array data has been modified, the updatePixels()
- * function must be run to update the changes.
- * <br><br>
- * Note that this is not a standard javascript array.  This means that
- * standard javascript functions such as <code>slice()</code> or
- * <code>arrayCopy()</code> do not
- * work.</p>

- *  save(myTable, 'myTable.csv',);  // Comma Separated Values

- * Returns the Perlin noise value at specified coordinates. Perlin noise is
- * a random sequence generator producing a more natural ordered, harmonic
- * succession of numbers compared to the standard <b>random()</b> function.
- * It was invented by Ken Perlin in the 1980s and been used since in
- * graphical applications to produce procedural textures, natural motion,
- * shapes, terrains etc.<br /><br /> The main difference to the
- * <b>random()</b> function is that Perlin noise is defined in an infinite
- * n-dimensional space where each pair of coordinates corresponds to a
- * fixed semi-random value (fixed only for the lifespan of the program; see
- * the noiseSeed() function). p5.js can compute 1D, 2D and 3D noise,
- * depending on the number of coordinates given. The resulting value will
- * always be between 0.0 and 1.0. The noise value can be animated by moving
- * through the noise space as demonstrated in the example above. The 2nd
- * and 3rd dimension can also be interpreted as time.<br /><br />The actual
- * noise is structured similar to an audio signal, in respect to the
- * function's use of frequencies. Similar to the concept of harmonics in
- * physics, perlin noise is computed over several octaves which are added
- * together for the final result. <br /><br />Another way to adjust the
- * character of the resulting sequence is the scale of the input
- * coordinates. As the function works within an infinite space the value of
- * the coordinates doesn't matter as such, only the distance between
- * successive coordinates does (eg. when using <b>noise()</b> within a
- * loop). As a general rule the smaller the difference between coordinates,
- * the smoother the resulting noise sequence will be. Steps of 0.005-0.03
- * work best for most applications, but this will differ depending on use.

- * result in greater than 1.0 values returned by <b>noise()</b>.

- * A class to describe a two or three dimensional vector, specifically

- * and direction can be accessed via the methods mag() and heading().

- * the object's position changes per time unit, expressed as a vector), and
- * acceleration (the rate at which the object's velocity changes per time
- * unit, expressed as a vector).
- * <br><br>

-   *  amplitude of the waveform at that sample of time.<br>
-   *  • <code>FFT.analyze() </code> computes amplitude values along the
-   *  frequency domain. The array indices correspond to frequencies (i.e.
