Resize vertical lanes

[sombrek]

Closes #2062

This makes resizing by handles and space tool work for vertical pools and lanes.

I just saw that ResizeBehavior.js, SpaceToolBehavior.js and their Spec files have Windows line endings that my IDE didn't make me aware of. They now have Unix-style line endings. Is that acceptable for you?

Hi, thanks for this PR! I am looking into this today.

I pushed line endings change before your commits to make the review easier. Other than that, I believe it's OK.

I'm sorry, I didn't manage to have a thorough review of this, but will have a look next week.

@barmac Don't worry. Thanks for the time you invest in the review.

I used the chance to make an adjustment.
There was one instance where I confused participant and lane in SpaceToolBehavior, I fixed that. The behavior remains the same.
I also added a small set of tests to cover more of my code.

Unfortunately, I created multiple commits. Please provide some squashing support when checking that in.

Once again sorry for the delay. The interaction is mostly good, but there is a difference in the minimal height when shrinking happens from the bottom and from the top:

BTW I've found an edge case which can be reproduced with horizontal participants as well. There is no need to fix this in this PR though. I wouldn't really bother creating an issue for this, too:

A challenge to solve in the future:

This problem can be noticed only if the participant contains child lanes.

@barmac Thank you very much for your thorough review. Glad you were able to make it.

I can reproduce this also for horizontal pools. I'd be happy if we could treat this as a pre-existing bug and not as a failure in the PR, just like the second issue you discovered.

A challenge to solve in the future:

This is actually on my list already, but out of scope for this PR. I plan to fix add/delete/split separately.

I was able to reproduce it for horizontal lanes too. Let's keep as is it then.
