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