No webgl in Chrome 22.0.1201.0 dev

[eee-c]

I'm fairly certain that this is a Chrome issue, but I figured I'd report it hear anyway.

Canvas's getContext('experimental-webgl') is returning null. This results in Gladius errors along the lines of Uncaught Error: already completed.

I have also tried just 'webgl' with no luck.

Even though this is likely a Chrome issue, it would be helpful to restore the commented alert("Could not initialise WebGL, sorry :-("). The current error is non-obvious and took a while to track down.
