aside: I wonder if this really should be 6. The skiafy script already rounds to
the nearest hundredth. Maybe we should be rounding to the nearest 50th? 10th?

From examining a random sample of icons on go/icons, two decimal places of
precision (where the last digit can be even or odd) looks to be the norm. I
don't really see much advantage of changing the rounding logic, and doing so
will have the effect of changing the literals provided by these SVGs in ways
that could (potentially) cause incorrect rendering of the icon.

[Evan Stade, 2016/06/27 22:41:14]

Yes, that would be because the skiafy tool rounds to the nearest hundredth.
Well if there were no rounding logic at all, we'd have random numbers like
5.9995838842. I took this to be an artifact of the authoring tool that Sebastien
uses, and that this might as well be 6. I arbitrarily decided to round to the
nearest hundredth. This 5.99 is making me wonder if that was the best decision.
But, like I said, this is an "aside" and not something you need to worry about
right now.

I was referring to the values inside the SVG source of the icons pulled directly
from go/icons before the skiafy tool has been used.
