Valis 8 prevent collision btw annot txts

[leepc12]

• Prevent collision between annotation names
• Increase the threshold of LoD (level of detail) for blending of annotation names to prevent fading-out too fast at higher LoD (zoomed-out).

Fixes:

• Annotation labels: labels overlap at some zoom levels VALIS-software/valis-hpgv#23
• Annotation labels: background color disappears on hover VALIS-software/valis-hpgv#24

Overall looks awesome! Most of my comments have to do with style conventions. Do you have a JS linting program installed? It can be really helpful.

The collision detection looks like it works really well. When I looked at your demo yesterday I saw a couple of overlaps but when I looked at it today I didn't see any.

One thing I was thinking could be another good change would be to not have the labels faded at the first zoom level at which they appear. They could just be black and then they'd be a lot more readable. I'm not sure what the use of having them faded is since they're not overlapping.

@leepc12 I have a comment marked as - Let's talk about. Let's talk about it. While I think the solution is clever, it does not solve the problem. I want to check with you to see if I am wrong. The other comments are minor Javascript rules.

One minor typo that I'd rather fix.

Also, can we make a release with this update?

Looks good
