volume step

[ims21]

Could be readed "audio volume step size" from e2 and apply it to volume in owif ?
F.eg. step is in e2 set as 5, then volume in owif will be 0, 5, 10 ... 100 too?
It would be good for volume graphic bar in skins.

If it's not there already, there's definitely already a comment in the code to do it .
