SV: Re: SV: [Dynapi-Dev] Widget constructor

hmm... well.. actually it's going to be initialized exactly as a dynlayer .. it has some specific functionality yes, but for the most part is, in essense a dynlayer.
I'll explain further:
    I'm creating a LayerMap for the API.
    That is, a layerwidget that is added on to another layer and functions as a transparent layer you can set "imagemaps" on.
    So it will have slightly less functionality then a dynlayer (you can't set HTML nor bgcolor etc.), and some extra stuff( event handling specific to certain areas that you set yourself etc.)
