correct me if i'm wrong, but i thought we had decided to have all widget 
inherit Plasma::LayoutItem directly?

this solves the problem of multiply inheriting GraphicsItem, which would be 
problematic for things such as QGraphicsTextItem, and keeps the hierarchy 
simple.

we can use the parent/child relationships that already exist in QGraphicsScene 
betwen QGraphicsItems.

the difference in API that i see right now between LayoutItem and Widget is 
that widget adds geometry, setGeometry, updateGeometry, invalidate (ugly 
name, btw =) and resize. 

invalidate can easily go away and the rest could be moved up into LayoutItem .

the additional parent/child relationships seem to duplicate what is already 
there in QGraphicsScene really.

i'd like to see us keep it simple and move with LayoutItem if at all possible.
