Cool!

Just a few comments:

• You can't use the id HTML property as this will not work when you have multiple similar windows open. The DOM spec only allows one unique ID. Use classNames instead, or like it was before the change: Create the element programatically.
• There's a gui-canvas element you can use
• There's also a gui-iframe element you can use
• You left an extra whitespace in the first line of scheme.html

Also, in my next commit I'm adding a internal fullscreen API, so you don't have to use a third-party one when that is done :)

Btw: You really should make a custom branch when making commits to official repositories. It's the only way to prevent problems if I decide to add something to your contribution.

Also, you can use this to implement mousewheel now:

Utils.$bind(element, 'mousewheel', function(ev, pos) {

  console.log(pos.z); // '-1' or '1' depending on direction

});
