- * /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 denisty 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):
- * <code><pre>
- * 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;
- *   }
- * }
- * </pre></code>
- *
- * <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>

- *  <p>Save an image, text, json, csv, wav, or html. Prompts download to
- *  the client's computer. <b>Note that it is not recommended to call save()
- *  within draw if it's looping, as the save() function will open a new save
- *  dialog every frame.</b></p>
- *  <p>The default behavior is to save the canvas as an image. You can
- *  optionally specify a filename.
- *  For example:</p>
- *  <pre class='language-javascript'><code>
- *  save();
- *  save('myCanvas.jpg'); // save a specific canvas with a filename
- *  </code></pre>
- *
- *  <p>Alternately, the first parameter can be a pointer to a canvas
- *  p5.Element, an Array of Strings,
- *  an Array of JSON, a JSON object, a p5.Table, a p5.Image, or a
- *  p5.SoundFile (requires p5.sound). The second parameter is a filename
- *  (including extension). The third parameter is for options specific
- *  to this type of object. This method will save a file that fits the
- *  given paramaters. For example:</p>
- *
- *  <pre class='language-javascript'><code>
- *
- *  save('myCanvas.jpg');           // Saves canvas as an image
- *
- *  var cnv = createCanvas(100, 100);
- *  save(cnv, 'myCanvas.jpg');      // Saves canvas as an image
- *
- *  var gb = createGraphics(100, 100);
- *  save(gb, 'myGraphics.jpg');      // Saves p5.Renderer object as an image
- *
- *  save(myTable, 'myTable.html');  // Saves table as html file
- *  save(myTable, 'myTable.csv',);  // Comma Separated Values
- *  save(myTable, 'myTable.tsv');   // Tab Separated Values
- *
- *  save(myJSON, 'my.json');        // Saves pretty JSON
- *  save(myJSON, 'my.json', true);  // Optimizes JSON filesize
- *
- *  save(img, 'my.png');            // Saves pImage as a png image
- *
- *  save(arrayOfStrings, 'my.txt'); // Saves strings to a text file with line
- *                                  // breaks after each item in the array
- *  </code></pre>

- *                                             save canvas as an image with

- *                                             depending on the filename.
- *                                             If object is provided, will
- *                                             save depending on the object

- *                                             above).
- *  @param  {[String]} filename If an object is provided as the first

- * Returns the Perlin noise value at specified coordinates. Perlin noise is

- * 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.

-/**
- * A class to describe a two or three dimensional vector, specifically
- * a Euclidean (also known as geometric) vector. A vector is an entity
- * that has both magnitude and direction. The datatype, however, stores
- * the components of the vector (x, y for 2D, and x, y, z for 3D). The magnitude
- * and direction can be accessed via the methods mag() and heading().
- * <br><br>
- * In many of the p5.js examples, you will see p5.Vector used to describe a
- * position, velocity, or acceleration. For example, if you consider a rectangle
- * moving across the screen, at any given instant it has a position (a vector
- * that points from the origin to its location), a velocity (the rate at which
- * 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>
- * Since vectors represent groupings of values, we cannot simply use
- * traditional addition/multiplication/etc. Instead, we'll need to do some
- * "vector" math, which is made easy by the methods inside the p5.Vector class.
- *
- * @class p5.Vector
- * @constructor
- * @param {Number} [x] x component of the vector
- * @param {Number} [y] y component of the vector
- * @param {Number} [z] z component of the vector
- * @example
- * <div>
- * <code>
- * var v1 = createVector(40, 50);
- * var v2 = createVector(40, 50);
- *
- * ellipse(v1.x, v1.y, 50, 50);

-  * Returns the Perlin noise value at specified coordinates. Perlin noise is a random sequence

-  * standard random() 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.
-  * The main difference to the random() 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). The resulting value will always be between 0.0
-  * and 1.0. Processing can compute 1D, 2D and 3D noise, depending on the number of coordinates
-  * given. 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.
-  * 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.
-  * 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
-  * noise() 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.

-    Creates an Abstract Syntax Tree -- "Light AST" from the Java-like code.
-
-    It is an object tree. The root object is created from the AstRoot class, which contains statements.
-
-    A statement object can be of type: AstForStatement, AstCatchStatement, AstPrefixStatement, AstMethod, AstClass,
-    AstInterface, AstFunction, AstStatementBlock and AstLabel.
-
-    AstPrefixStatement can be a statement of type: if, switch, while, with, do, else, finally, return, throw, try, break, and continue.
-
-    These object's toString function returns the JavaScript code for the statement.
-
-    Any processing calls need "processing." prepended to them.
-
-    Similarly, calls from inside classes need "$this_1.", prepended to them,
-    with 1 being the depth level for inner classes.
-    This includes members passed down from inheritance.

-      * with the ones of pixels in the destination image (B):
-      * BLEND - linear interpolation of colours: C = A*factor + B
-      * ADD - additive blending with white clip: C = min(A*factor + B, 255)
-      * SUBTRACT - subtractive blending with black clip: C = max(B - A*factor, 0)
-      * DARKEST - only the darkest colour succeeds: C = min(A*factor, B)
-      * LIGHTEST - only the lightest colour succeeds: C = max(A*factor, B)
-      * DIFFERENCE - subtract colors from underlying image.
-      * EXCLUSION - similar to DIFFERENCE, but less extreme.
-      * MULTIPLY - Multiply the colors, result will always be darker.
-      * SCREEN - Opposite multiply, uses inverse values of the colors.
-      * OVERLAY - A mix of MULTIPLY and SCREEN. Multiplies dark values, and screens light values.
-      * HARD_LIGHT - SCREEN when greater than 50% gray, MULTIPLY when lower.
-      * SOFT_LIGHT - Mix of DARKEST and LIGHTEST. Works like OVERLAY, but not as harsh.
-      * DODGE - Lightens light tones and increases contrast, ignores darks. Called "Color Dodge" in Illustrator and Photoshop.
-      * BURN - Darker areas are applied, increasing contrast, ignores lights. Called "Color Burn" in Illustrator and Photoshop.
-      * All modes use the alpha information (highest byte) of source image pixels as the blending factor.
-      * If the source and destination regions are different sizes, the image will be automatically resized to
-      * match the destination size. If the srcImg parameter is not used, the display window is used as the source image.

-    * hint(ENABLE_OPENGL_4X_SMOOTH) - Enable 4x anti-aliasing for OpenGL. This can help force anti-aliasing if
-    * it has not been enabled by the user. On some graphics cards, this can also be set by the graphics driver's
-    * control panel, however not all cards make this available. This hint must be called immediately after the
-    * size() command because it resets the renderer, obliterating any settings and anything drawn (and like size(),
-    * re-running the code that came before it again).
-    * hint(DISABLE_OPENGL_2X_SMOOTH) - In Processing 1.0, Processing always enables 2x smoothing when the OpenGL
-    * renderer is used. This hint disables the default 2x smoothing and returns the smoothing behavior found in
-    * earlier releases, where smooth() and noSmooth() could be used to enable and disable smoothing, though the
-    * quality was inferior.
-    * hint(ENABLE_NATIVE_FONTS) - Use the native version fonts when they are installed, rather than the bitmapped
-    * version from a .vlw file. This is useful with the JAVA2D renderer setting, as it will improve font rendering
-    * speed. This is not enabled by default, because it can be misleading while testing because the type will look
-    * great on your machine (because you have the font installed) but lousy on others' machines if the identical
-    * font is unavailable. This option can only be set per-sketch, and must be called before any use of textFont().
-    * hint(DISABLE_DEPTH_TEST) - Disable the zbuffer, allowing you to draw on top of everything at will. When depth
-    * testing is disabled, items will be drawn to the screen sequentially, like a painting. This hint is most often
-    * used to draw in 3D, then draw in 2D on top of it (for instance, to draw GUI controls in 2D on top of a 3D
-    * interface). Starting in release 0149, this will also clear the depth buffer. Restore the default with
-    * hint(ENABLE_DEPTH_TEST), but note that with the depth buffer cleared, any 3D drawing that happens later in
-    * draw() will ignore existing shapes on the screen.
-    * hint(ENABLE_DEPTH_SORT) - Enable primitive z-sorting of triangles and lines in P3D and OPENGL. This can slow
-    * performance considerably, and the algorithm is not yet perfect. Restore the default with hint(DISABLE_DEPTH_SORT).
-    * hint(DISABLE_OPENGL_ERROR_REPORT) - Speeds up the OPENGL renderer setting by not checking for errors while
-    * running. Undo with hint(ENABLE_OPENGL_ERROR_REPORT).
-    * As of release 0149, unhint() has been removed in favor of adding additional ENABLE/DISABLE constants to reset
-    * the default behavior. This prevents the double negatives, and also reinforces which hints can be enabled or disabled.
