In some situations we can get into resizeSections in a hidden QHeaderView. If the headerView is hidden then we look at all the rows, and that can be extemely expensive for a large model. This patch limits the sizeHint with only looking at a maximum 1000 rows. Though this is more inaccurate it is also faster - and it is not much different from what QTreeView does.
