Subject: changed WidgetLayer to a new (well partial) image storage

WidgetLayer is now to be considered stable.
there wont be any api removals.

newwidget.{h,cpp} will inherit WidgetLayer, soon.
i will try to be logic compatible with current widget.{h,cpp}, but will NOT
guarantee api compatibility.
