Title: this derives the scale quantity

android does not supply event.scale, so d3 freezes on android multi touch input. this == ++bad. I create a new variable in zoom.js representing the on touch distance between fingers, and normalize the distance at touchmove to that for the missing scale value. works like Jesus on a weekday. nexus 7 development environment ftw. -dru
