  to me the real problem is really the default settings for durations 
longDuration became 150ms or so, (shortduration is something so short that 
usually the animation frames just gets dropped altogether so it's pointless to 
even use it ever)
  I know this was done in the attempt of improving animations, but the end 
effect is ridiculous and makes animations actually looking worse, either 
comically fast (super fast fades are ok, item movements or resizes shouldn't 
actually be too fast, or be perceived as threatening) or no frames rendered at 
all even if there is code for it
  the original default values of 150 and 250 msecs for short and long were 
quite fine actually
  
  also, we should probably start into looking using SmoothedAnimation speed 
more rather than durations (to not fix travel time, but travel speed) (as 
animators don't support it and we would need something that reacts to global 
animations settings probably we would need our implementation of the speed 
concept)
