Crash switching scene modes

[mramato]

Run http://localhost:8080/Apps/Sandcastle/index.html?src=Labels.html and continually switch between 2D/3D mode (no need to do anything else), you will randomly crash:

DeveloperError: normalized result is not a number

@bagnell any ideas?

[mramato]

We're always in the middle of a morph when the crash happens and the camera position looks like it's at least partially NaN

This issue is marked for next release, so we should try to get in a fix for next week. Who would be best to look at this? @bagnell?

Yes, @bagnell
