chapter-01/02-first-scene.html doesn't render on Chrome Version 46.0.2490.80 (64-bit)

[NAThompson]

Error message from Javascript console:

Uncaught TypeError: Cannot read property 'getShaderPrecisionFormat' of null

This line is responsible:
var renderer = new THREE.WebGLRenderer();

However, it does render on Firefox. OS: Ubuntu 15.04.

Works fine in 46.0.2490.71 (slightly earlier build)

One search of this error led me to:

Inferring that may be a problem with Chrome in general. Check your GPU against the Chrome WebGL blacklist for all OSes and Linux.

You should try getting past the backlist that Chome uses. Open "chrome://flags/" in your browser and enable the flag called "Override software rendering list".
You can also take a look at "chrome://gpu/" to see if any problems pop up.
