- Prevent UITableView contentInset property from affecting its backgroundView?
- _backgroundImageView = [[UIImageView alloc] initWithFrame:backgroundRect];
- [_backgroundImageView setImage:...];
- [_backgroundImageView setContentMode:UIViewContentModeBottom];
- [self setBackgroundView:_backgroundImageView];
- [_tableView setContentInset:UIEdgeInsetsMake([_topBarView frame].size.height, 0, 0, 0)];
