	{
		canvas: document.getElementById( 'myCanvas' ), // optional
		width: 1024,        // optional
		height: 576,        // optional
		duration: 1000,     // optional

• instance.remove( order )
• instance.replace( images )
• instance.to( to )
• instance.setEffect( effectName [, uniforms ] )
• instance.destroy()

Editable params

• instance.domElement
• instance.inTransition
• instance.length
• instance.currentIndex
• instance.prevIndex
• instance.nextIndex
