the first issue... the 'decorate' method of the DecorationStyle class
was not in the X monad (I try to write pure code only, lately...;)

So I changed that: now it is returning a X (Maybe Rectangle). But I
added a pureDecoration method too. This way we can define Tabbed,
DwmLike and Simple with pure functions.... cool isn't it?

Cheers,
