 * Deprecated in 2.0, to be removed in 2.1.

 * These three globals carry a 1.x typo in their prefix: gtp4wp_, not gtm4wp_.
 * Nothing inside the plugin reads them. They are set only for third-party code
 * written against 1.x, which is why the typo was never worth correcting.
 *
 * A global variable cannot raise a deprecation notice the way a function can, so
 * this comment and the changelog entry are the only warning a consumer gets.
 *
 * Replacements, available on both admin and frontend requests and defined at the
 * same point in the load order:
