         *   width and height parameters. .pixels gives access
         *   to an array containing the values for all the
         *   pixels in the display window. These values are
         *   numbers. This array is the size (including an
         *   appropriate factor for the 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.
         *   See .pixels for more info. It may also be simpler
         *   to use set() or get().
         *
         *   Before accessing the pixels of an image, 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.

         *   you may wish to send the frames to a server where
         *   they can be stored or converted into a movie. If
         *   no callback is provided, the browser will pop up
         *   save dialogues in an attempt to download all of

         *   callback provided the image data isn't saved by
         *   default but instead passed as an argument to the
         *   callback function as an array of objects, with the
         *   size of array equal to the total number of frames.
         *   The arguments duration and framerate are
         *   constrained to be less or equal to 15 and 22,
         *   respectively, which means you can only download a
         *   maximum of 15 seconds worth of frames at 22 frames
         *   per second, adding up to 330 frames. This is done
         *   in order to avoid memory problems since a large
         *   enough canvas can fill up the memory in your
         *   computer very easily and crash your program or
         *   even your browser.
         *
         *   To export longer animations, you might look into a
         *   library like ccapture.js.

         *   equal to 22.

         *   executed to handle the image data. This function
         *   should accept an array as argument. The array will
         *   contain the specified number of frames of objects.
         *   Each object has three properties: imageData - an
         *   image/octet-stream, filename and extension.
