TopRight() is wrong (type),  it's bottomRight().

I don't understand what you want to say. Are you saying that our rect 
conversion is ok ? (I don't care for +1 -1 at the moment).
QAbstractScrollArea->viewport() uses TopLeft for information about viewport 
origin when we ask QWidget_rect(viewport, @R);
When we move scrollbar , viewport moves, QWidget_rect() is always same, but 
viewport is changing QRect topLeft value (according to qt code).

If we move viewport (eg. by scrolling) qt code says that TopLeft = (0, -20) in 
qt bindings it says TopLeft = (0,0).
I'll try to add it to bindings just to see if it works.
