    don't call cogl_set_default_context in hello.c
    
    Actually calling cogl_set_default_context isn't required because
    cogl_context_new implicitly sets the new context to be the default
    context. Since we want to eventually get rid of the concept of a default
    context we'd rather not pollute the example with the concept.
