it'd be possible - sure. in edje map+embryo could do this no problems. if the
thing uses a dragable it can be done - make the dragable invisible and just
have the embryo + map etc. control the dragable (and listen to dragable value
changes coming from code).

as for logarithmic stuff - it isnt edje's job to do that - if anything it's the
mixer code - though we can argue that it should be alsa's job to present a
universal control that is always the same way (if hw control is linear or
logarithmic - the driver knows and figures it out).
