Instead of defining CLUTTER_ENABLE_EXPERIMENTAL_API and COGL_ENABLE_EXPERIMENTAL_API in individual source files, enable them on the command line. We weren't tracking exactly what pieces of experimental API we were using and we were using the experimental API in most source files that used Clutter and Cogl, so the local #defines were annoying rather than useful. https://bugzilla.gnome.org/show_bug.cgi?id=685463
