/// A generic container which can layer multiple styleboxes over/under the
/// contents of of the child controls. This container contains two forground
/// panels and two background panels, each of which can be styled independently.
/// Background panels will be rendered underneath the child controls, while
/// foreground panels will be rendered above. The use of two panels for each
/// level allows for one level to use a stylized graphic, typically including
/// some modulation to color-match the surrounding UI, while the second level
/// can be used for shadows or highlights, which would typically not have such
/// modulation.
