new BaseTexture(source:String, ..) should be Element

[bartvanheukelom]

The mapping of the BaseTexture constructor is wrong. source is declared a String but it should be js.html.Element so it can take an Image or a Canvas. Or define 2 overloads, if that's possible.

 /**
  * @param source {Image|Canvas} the source object of the texture.
  */
 function new(source:String, ?scaleMode:Int, ?resolution:Float);
