Do not reload launcher when changing active display

Browse Source 
> Updating IDP to use fixed bitmap sizes, so that the cache
  stays valid
> Caching last known windowMetrices for non-active displays and
  using estimation only when the cache is not available
> Only reloading model if IDP change could have affected the model
> Remove unnecessary listeners from IDP which are already controlled by
  model lifecycle
