[question] SoundFileView - channel spacing

In further work on improving SoundFileView (to be able to use it for
variety of plotting scenarios) I'm adding the ability to offset the view
vertically, and also change the spacing between channels.

Currently, SoundFileView displays (n+1) number of spaces for every (n)
number of channels:

While I think this looks fine, it makes harder to calculate where the
values on the y axis are (of course it's possible, but arguably convoluted,
especially in case one wanted to superimpose a gird from sclang on top of
it, or even label reference values).
Also, exposing control over spacing would be awkward - either setting
spacing ratio would result in automatically calculated channel
height/ratio, or setting channel height would make the spaces automatically
calculated (in each case the two ratios would not add up to 1).
I'm thinking about making the top and bottom space half of the current
value:

Then all the channels are equally distributed inside the view. I think it's
a more "proper" approach allowing better labeling etc, but I also think it
looks a little worse than the current implementation.

What are your thoughts?

Thanks,
Marcin
