    glarea: Drop the dispose vfunc
    
    This was causing us to leak, in the following scenario:
    1) gtk_widget_destroy is called on a GL area
    2) dispose is run and clears the context
    3) the GL area is unrealized, but the context is already cleared,
       so we leak all the GL buffers
