Bad matrix in Canary

[emackey]

This appears to be a Canary-only issue for now, but probably worth investigating.

In Chrome Canary 30 with b19 master, Incognito mode, load up Cesium Viewer and switch to 2D mode. At the end of the morph:

matrix is not invertible because its determinate is zero.

This was originally reported to me as a more complex bug: Load simple.czml into Viewer and follow a satellite, then switch to 2D and wait for the morph to complete, and then switch to Columbus View. The same type of error message appears at the start of the morph to CV.

I actually want to avoid the inversion for some matrices altogether with Gauss-Jordan elimination. CC #419. It could fix this issue if it turns out to be a real problem.

I think this went into Chrome 29, released yesterday. See linked issue.

I see it in Chrome stable now too.

Yeah, they are definitely the same bug. We'll close them both once the fixes are in.
