  • Switching from the GDK to Cairo APIs and dropping lots of old GDK code (such as GdkGC and GdkImage) was done to improve GTK+ semantics and making it easier to port GTK applications to other platforms like Windows and Mac OS X, to tap into new features of the Cairo API rather than the outdated GDK drawing API, and to improve the drawing performance especially in cases where the GPU is utilized.
