Consider bringing back 'observed area' feedback

[jonfroehlich]

We tracked and visualized the observed area in Tohme's top-down map--and actually forced workers, I believe, to look 360 degrees before submitting their work:

@shokiami and I talked about this today and I think it's a great task for him to take on this quarter! Just showing this feedback to users will encourage them to audit more carefully (even if we don't force them to look everywhere). I think it can also encourage users to label things more close to them if we let the this observed area only extend a short-ish distance from where you're located!

Nice, great idea. Looking forward to seeing what you can come up with @shokiami!

Just wanted to share what it currently looks like!

Ooo, nice progress Sho! Possible to extend the"fog of war" polygon so it fills up the whole map? Does the polygon take into account what you've observed from previous screens (i.e., locations you've just been traveling from).

Yup, it's possible! I have two constants I'm using which represent the width and height of the canvas (in latitude and longitude). That being said, I feel like the smaller box better represents the area the user can see at the moment. Thoughts?
Also, I just added the functionality so that the polygon takes into account what you've observed from the previous screen! Take a look:

1. Let's say a user fully scanned an area.

2. This is what they would see when they take a step!

Also, for reference, this is what it looks like when I don't clear the previous region when stepping. The calculation essentially entails finding where the two regions intersect.

I think you want to use something like this, but the polygons should probably be combined to just a single polygon so that you aren't seeing something different on the overlap. You can see all the examples @isavin12 added in #1324 do it that way. But maybe that was always your plan and you're just showing progress as you go along :)

@shokiami and I discussed this on our call today. We decided that either the "fog-of-war" should take up the whole top-down map—as now, it's only a subset as a small square—or, instead of the square, we could do a circle.

@shokiami also mentioned using the turf.js library to engineer this in the future.
