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.
