title: Offset UISlider Min/Max value images
body: <p>I'm trying to offset the x/y position of a UISlider's min and max value images. 
  Currently, I'm sublcassing UISlider and am setting the maximum value image like this:</p>
  
  <pre><code>[self setMaximumValueImage:[UIImage imageNamed:@"circle_with_plus"]];
  </code></pre>
  
  <p>However, I need this image to be closer to the actual UISlider and have little control over visual assets on this project. I've tried using </p>
  
  <pre><code>- (CGRect)maximumValueImageRectForBounds:(CGRect)bounds
  </code></pre>
  
  <p>However, I'm my min/max value images may change size dynamically so I'm not sure how to properly implement it in this case. Is there a different way to move the asset?
  Thanks</p>
