Tree: needed options for disable/enable the animation when expanding/collapsing nodes

[Sergey Kravchenko]

For large trees, the effects are not needed, but now it is hard-coded.

The effects aren't needed for small trees either. Are you having a particular problem with large trees? One thing on my list is to consider is to replace all/most of the JS animations with CSS animations, which would make this easier to customize.

Client has asked me to remove the animation (he does not like animation). To this end, had to inherit dijit._TreeNode and clean animation. I decided my problem, though, if it were possible, it would be easier in future:

new dijit.Tree({
  animation: false
});

OK. Note that you can also set dijit.defaultDuration to 1, that should make it seem like there's no animation.

Duplicate of #14251.
This will be handled as part of the general changes to use CSS animations instead of javascript ones.
