treeview: if we are below rows that changed height: redraw
We have to redraw if we are below a couple of rows that changed height in do_validate_rows(). This will still require a redraw for a large amount of cases, can we do better? You would expect that a redraw of the tree view is not required when the dy changes with the same delta as the delta of the height accrued when validating the nodes. This further optimization will likely require changes to the top_row/dy synchronization code.
