The way you are supposed to use the API for something like that is to create a
shape_plan first, and use hb_shape_plan_get_shaper() and strcmp to "graphite2".

I pushed out the new API now.  Looks to me like it should indeed only return
non-NULL in cases that graphite2 backend will be used by default, though I've
not tested those.  The API is a bit different from what Martin provided.
