Comment (by mcs):

 Kathy and I experimented with the code on Mike's branch.  This is looking
 quite good!  Here are a few things we observed:

 1. Clicking a label sets the wrong slider position (fallout from reversing
 the positions).

 2. We found that the alignment of the labels to the slider positions can
 be improved by removing flex from the first <description> hbox (to get
 more of a 1/3, 1/3, 1/3 split).

 3. On a Ubuntu 14.04 system, the height of the preferences window and
 slider changed when we switched to the Medium-High and High slider
 positions (the help text is too tall and/or the area for it is too
 narrow). It is OK but kind of a weird experience (and maybe it only
 happens on some systems).

 We have a patch for issues 1 and 2 which I will attach in a moment.
