Issue with the animation pattern implementation.

[francois2metz]

There is a bug with your Animation pattern implementation.

Buffer = {
  commands: [],

  // Adds a command to the buffer, and executes it if it's the only command
  // to be ran.
  add: function(fn) {
    this.commands.push(fn);
    if (this.commands.length == 1) fn();
  },

  // Moves onto the next command in the buffer.
  next: function() {
    this.commands.shift();
    if (this.commands.length) this.commands.shift()();
  }
};

The add function should not call the callback fn but call next instead.

Buffer = {
  commands: [],

  // Adds a command to the buffer, and executes it if it's the only command
  // to be ran.
  add: function(fn) {
    this.commands.push(fn);
    if (this.commands.length == 1) this.next();
  },

  // Moves onto the next command in the buffer.
  next: function() {
    if (this.commands.length) this.commands.shift()();
  }
};

Cannot provide a pull request because your master branch is not up to date.

Bye,
François
