Challenge: Button Themes
After completing the 9-patch image update, you may notice that something is not quite right with the background of your buttons. Behind the dog ear, you can see something that looks like a shadow. As you press the button, it appears to come closer to your finger.
Your challenge is to remove that shadow. Use your new theme spelunking skills to determine how the shadow is applied. Is there some other type of button style that you can use as your parent for the BeatBoxButton style?
