In some ways, this is unrelated, but I had to combine this anyhow:

* Extend the PaneSwitch BControl from Tracker, so it can draw on/off labels.
  This has the added benefit that you can click the label to expand/collapse,
  like for example in the Get Info window (Permissions).
* I also added font-sensitivity features to PaneSwitch, and it can be used
  in layouted windows (untested).
* This made the "DrawButton" in the Installer superfluous.
