// ContentSettingBubbleContents is used when the user turns on different kinds
// of content blocking (e.g. "block images").  When viewing a page with blocked
// content, icons appear in the omnibox corresponding to the content types that
// were blocked, and the user can click one to get a bubble hosting a few
// controls.  This class provides the content of that bubble.  In general,
// these bubbles typically have a title, a pair of radio buttons for toggling
// the blocking settings for the current site, a close button, and a button to
// get to a more comprehensive settings management dialog.  A few types have
// more or fewer controls than this.
