the widget() in khtmlview is there just to govern the scrollbars (i.e. to 
represent the document size), it really doesn't have any other purpose.

So no, the painting code is appropriately placed.

the thing is our needs are in-between QAbstractScrollArea (slightly too low 
level) and QScrollArea.

So we use QScrollArea in a slightly unusual, rather low-level way.
