[cogl/wip/rib/cogl-1.12: 5/101] Add a context member to CoglPath

[Robert Bragg <rbragg src gnome org>]

commit 9cda94bd7c75ec2b9c2ca3de0c9fe2ed7a18e8b8
Author: Neil Roberts <neil linux intel com>
Date:   Mon Apr 16 13:21:15 2012 +0100

    Add a context member to CoglPath
    
    cogl_path_new now takes a CoglContext pointer which it keeps a pointer
    to instead of relying on the global context.

    (cherry picked from commit afc63f8211c230f8fd1f7801f9085627c46a8661)
    
      Since we can't change the api on this branch this just applies
      the internal cleanups so we depend less on _COGL_GET_CONTEXT
