REVISION SUMMARY
  In order to pick the next client to activate we traverse the stacking
  order from bottom to top and assign to each client a score. The client
  with the best score will be activated next. Function that assigns score
  bases its decisions purely on geometry. This may backfire if there are
  couple maximized or fullscreen clients on the screen - we'll activate
  the bottom-most client.
  
  This change toggles direction we traverse the stacking order. If there
  are several clients with an identical score, then prefer the top-most
  client, the one that the user most likely sees at the moment.
