 // Google Chrome must depend on GTK 2.18, at least until the next LTS drops
 // (and we might have to extend which version of GTK we want to target due to
 // RHEL). To make our porting job for GTK3 easier, we define all the methods
 // that replace deprecated APIs in this file and then include it everywhere.
 //
 // This file is organized first by version, and then with each version,
 // alphabetically by method.
