Layout animation bug

[ugurdogrusoz]

This was discovered by @hasanbalci:
Open up daily Newt, set animation true (perform animation during layout), set incremental off (randomize: true) and perform layout on default graph. You'll see that at the very end of layout things get messed up (compounds placed in weird locations):

This doesn't happen when animation if off (animation is set to 'end'). I don't know if this is somehow related to #45.
We suspect this was introduced after tiling was moved in l-level.

@ugurdogrusoz I made the requested change for #45 and it did not solve this problem as I expected (Because that change is inside if(this.options.animate !== 'during'), but in this case animate option is 'during').

Then, in cose-bilkent go back to v1.6.7 where tiling is not moved to l-level yet. I see that this problem does not appear in v1.6.7. It appeared right after tiling is moved to l-level as you suspected.

@ugurdogrusoz it seems to be fixed now.

@hasanbalci can you verify and close the issue please?
