[Laszlo-dev] Mixins in swf9

[André Bargull]

Mixins produce only an empty interface declaration for swf9? The 
description of LPP-5266 says:
> 1) It should output an `interface`, that consists of the signature of 
> the mixin, i.e., all the method declarations. This will make it so 
> `instanceof` can work on mixins.

So (1) wasn't implemented? For example LzDataElementMixin will be 
transformed to:
> package {
> interface LzDataElementMixin {
> }
> }

But I've expected:
> package {
> interface LzDataElementMixin {
>   function insertBefore (newChild, refChild);
>   function replaceChild (newChild, oldChild);
>   function removeChild (oldChild);
>   [...]
