Bug description:
  [ Impact ]

  When multiple non-maximised windows of the same program are open and
  one clicks on the icon of the program in the launcher, they are all
  shown one next to each other but in an unexpected, difficult-to-
  predict order: windows that are in the top-left corner of the
  workspace can be shown in the exposé in the right bottom position or
  on the left bottom corner.

  This makes very hard to switch between similarly looking windows like
  terminals.

  [ Test Case ]

  
  * launch four or so terminal windows;
  * write something different on each of them to be able to tell them apart;
  * move each window to a different corner, possibly using the auto-resizing feature of Unity;
  * click on the terminal icon in the launcher;
  * many terminal windows are displayed;
  * choose the thumbnail in the right-top corner;
  * very likely a window that was in another corner has been selected;
  * try again various time and realize how confusing this all is.

  [ Potential Regressions ]

  An invalid ordering calculation might still position windows in the
  exposé in unexpected ways.  This is not a serious regression and has
  not been observed under production situations.

  [ Additional Info ]

  The Ubuntu 14.04 LTS SRU was cherry-picked from upstream Unity as
  released in Ubuntu 14.10 where it demonstrated stability under daily
  use.
