    st: Stop checking for ClutterTexture
    
    _st_create_shadow_pipeline_from_actor creates shadow pipelines
    from actors. This function special-cases ClutterTexture as a
    small performance improvement, since we can have access to the
    CoglTexture easily with it. However, recent commits removed all
    usage of ClutterTexture from GNOME Shell, rendering this optimization
    useless.
    
    Remove the optimization from _st_create_shadow_pipeline_from_actor.
