Summary:
When using a fully customized MPVolumeView, the minimum track image is not resized correctly if the volume view is initially shown in landscape, and then a rotation to portrait occurs. The autoresizing masks are set correctly.

Steps to Reproduce:
- Create an instance of MPVolumeView.
- Set a custom minimum track image for the volume view, using the setMinimumVolumeSliderImage:forState: method.
- Set a custom maximum track image for the volume view, using the setMaximumVolumeSliderImage:forState: method.
- Set a custom thumb image for the volume view, using the setVolumeThumbImage:forState:.
- Show the containing view in landscape mode (with the attached sample project: start the application in landscape mode)
- After viewing the volume view correctly in landscape, rotate to portrait.

Expected Results:
A perfectly fine slide animation of the thumb image, with the normal behaviour for all the slider image view components.

Actual Results:
When rotating to portrait, the minimumVolumeSliderImage is shown beyond the borders of the volume view, which seems to be resized correctly but does not clip the minimumVolumeSliderImage.
