While working with bug 430851, I found that SpaceTreeLayout can be unreasonably slow. After some evaluation I found that it relates to animations turned on. I believe, it is the same thing experienced in the forum post: https://www.eclipse.org/forums/index.php/t/673977/

I don't have time now to debug this further, but I change the defaults of the algorithm not to turn on animation, and report back on the forum with this workaround. However, I leave this issue open for a real fix in the future.

As animation support should IMHO not be positioned inside layout at all, I pushed the following changes to origin/master:

- Removed animate option from SpaceTreeLayoutAlgorithm.
- Adjusted ILayoutContext.flushChanges() to no longer accept an animation hint (this was only used by SpaceTreeLayoutAlgorithm). Adopted all implementers.

Thereby resolving this as fixed in 3.11.0 M5.
