Do not modify the changed() status of rows when no drawing has taken place
There are several places in the code where a row is painted with drawing
disabled in the painter. The goal is only to recompute inset positions.
Such a case happens in BufferView::checkCursorScrollOffset, as part of the
horizontal scrolling patch.
It makes sens to consider that only a real painting of a row should change
its status. However, I would not be surprised if this change would break other
things.
Fixes: #9388
