  10 // Google Chrome must depend on GTK 2.18, at least until the next LTS drops
  11 // (and we might have to extend which version of GTK we want to target due to
  12 // RHEL). To make our porting job for GTK3 easier, we define all the methods
  13 // that replace deprecated APIs in this file and then include it everywhere.
  14 //
  15 // This file is organized first by version, and then with each version,
  16 // alphabetically by method.
  17 //
  18 // For Google Chrome builds, we want to support RHEL 6, which uses GTK 2.18,
  19 // but the official builder is Ubuntu Lucid with GTK 2.20. Thus for Google
  20 // Chrome builds, we define the GTK 2.20.0 compatibility functions even though
  21 // the system GTK provides the functions.
