day/night visualization

Hi Bruno,

We are aware of the strange 2D/columbus view lighting when the time-based lighting is turned off. It’s pretty simple to fix, and I plan to do it when I tackle other lighting improvements: https://github.com/AnalyticalGraphicsInc/cesium/issues/10.

Do you have screen shots for when day/night lighting looks different between 2D and columbus view? I do not see it.

Regards,

Patrick
