Summary:
When using setBackgroundImage:forState:barMetrics on UISegmentedControl the highlight state image shows on touchDown regardless of the rest of the state mask that's been set.

In the attached project a UISegmentedControl subclass is set up with the following images / states:

    [self setBackgroundImage:[UIImage imageNamed:@"UISegmentedControlBackgroundUnselected"]
                    forState:UIControlStateNormal
                  barMetrics:UIBarMetricsDefault];
    
    [self setBackgroundImage:[UIImage imageNamed:@"UISegmentedControlBackgroundSelected"]
                    forState:UIControlStateSelected
                  barMetrics:UIBarMetricsDefault];

    [self setBackgroundImage:[UIImage imageNamed:@"UISegmentedControlBackgroundSelected"]
                    forState:UIControlStateHighlighted|UIControlStateSelected
                  barMetrics:UIBarMetricsDefault];
    
    [self setBackgroundImage:[UIImage imageNamed:@"UISegmentedControlBackgroundHighlighted"]
                    forState:UIControlStateHighlighted|UIControlStateNormal
                  barMetrics:UIBarMetricsDefault];

When tapping on a selected UISegment, the highlighted state is displayed, even though a different image is set for the UIControlStateHighlighted|UIControlStateSelected state.

The attached project demonstrates this.

Steps to Reproduce:
1. Create an example 1 view project.
2. Add a UISegmentedControl and set it's class to a UISegmentedControl subclass
3. In awakeFromNib, set backgroundImages fro the normal, selected, highlighted and highlighted+selected states.
4. Run the app. Tap the control to select a side.
5. Tap and hold on the same segment. 
7. It will show the Normal+Highlighted image instead of the Selected+Highlighted image.

(See attached sample project)

Expected Results:
The selected+highlighted image should be displayed.

Actual Results:
The normal+highlighted image is displayed.
