	The rising mirror image: 0 at x = 0, 1 at x = 1. With k > 0 it's fast at the start, like an RC charge.

	Inverse of rising(): where on the segment the curve reaches value. Not for the render path (uses log2).

Detailed Description

A falling segment from 1 at x = 0 to 0 at x = 1, normalised so its length doesn't depend on its shape.

k is how many octaves (6 dB steps) an unnormalised exponential would fall over the segment:

k = 0 is a straight line
k > 0 is a decaying exponential, steep at the start
k < 0 bends the other way: slow at the start, steep at the end The Deluge's original lookup tables decayTableSmall4 and decayTableSmall8 are exactly k = 4 and k = 8.
