D18000: Modernize easing function of slidingpopups effect.

zzag added a comment.


  The main problem I see is that it's too rapid, imho. It's not very pleasant to watch how some entity moves too rapidly. Usually, such kinds of animations start from some predefined position. For example, if we want to use a scale animation to introduce some entity, it is preferred to animate the scale, say, from 0.8-0.9 to 1.0, instead of from 0.0 to 1.0.*
  
  I'd like to see some analysis of what's wrong with the current choice of easing curves, how it can be fixed, and why we picked this easing curve instead of that, so we have a "bigger picture" of what should be done.
  
  * There are exceptions.
