   5 // A struct for managing browser's settings that apply to the renderer or its
   6 // webview.  These differ from WebPreferences since they apply to Chromium's
   7 // glue layer rather than applying to just WebKit.
   8 //
   9 // Adding new values to this class probably involves updating
  10 // common/view_messages.h, browser/browser.cc, etc.
