[Audacity-devel] I'm working on a fix for note track zooming

[Pokechu22 <pok...@gm...>]

I'm currently working on a pull request that'll change note track zooming
to store the bottom and top notes instead of the pitch height.  It also
includes a fix for bug 1815
<http://bugzilla.audacityteam.org/show_bug.cgi?id=1815> (since the bottom
and top notes are now specified, it's now trivial to default to showing all
notes), and additional fixes for bug 1819
<http://bugzilla.audacityteam.org/show_bug.cgi?id=1819> and bug 1820
<http://bugzilla.audacityteam.org/show_bug.cgi?id=1820>.

I also changed the behavior of "Zoom Reset" to only zoom so that the top
and bottom notes are the actual highest and lowest ones in the song; I've
added a "Max Zoom" that has the old functionality.  (Shift+Right-click
shows the highest and lowest notes unless that's already the zoom in which
case it does max zoom, which feels like a good blend of the behavior).

I'm not entirely confident on those names, and with the impending string
freeze (which I wasn't aware of) I figure it's better to ask for advice on
those names now than when I actually submit the PR.

The PR itself isn't done yet but I think I can get it finished later today
(right now I'm just tidying everything up).
