Fixes
Selection.orderalgorithm which had exponential complexity for no good reason.In the below video, top is before this PR and bottom is after. Uses the desktop sample app, but with the number of elements in the sine wave cranked up.
speed-differential.mp4
Briefly toyed with a direct port of D3's order function. Doing so exactly matched its output orderings, which this implementation doesn't, but both increased complexity and decreased runtime speed.
