doc: regenerate SVGs for Animation easings.

I did that just to be sure that 3c8fd70c12 didn't break anything, but to my surprise arrived at a difference somewhere completely different. The problem is that the SVGs were generated before Math::pack() was fixed in e62ce4faa6 (Feb 2019) to perform correct rounding, and so most color values were off by one. Heh.
