The implementation for QTreeViewPrivate::intersectedRect() calculated
the view rect for every single index which is not needed:
- when the row is spanned, the first item spans the complete viewport
- the x-position of an index in the same column but different row is
the same so no need to re-calculate the boundaries again (similar to
the implementation in QTableView)
This reduces the visualRect() call count from n*m to n+m
