  Special effects.

  Ivan notes: 
  - duration 0  = endless ( it lasts al long as the others are active). 
  - duration -1 = like 0, but disabled when fade starts
  If there are only endless ones, the fx is self-removed instantly unless "manualRemove" is set.

  - delay -1 = activated when fade starts
  If "manualRemove" is not set the fx will self-remove after the max "duration" value.
