···11+u/distortion: Improve Index distortion and tidy code. While this touches the
22+Vive distortion code all Vive headsets seems to have the center set to the same
33+for each channel so doesn't help them. And Vive doesn't have the extra
44+coefficient that the Index does so no help there either.
