Retain Globe Curvature at higher zoom levels and/or when camera tilted

[chrisdalke]

Motivation

With the 3D globe projection, the globe curvature is reduced based on zoom level. When the camera is tilted, this transition is jarring for a few reasons:

• Users with camera tilted can see tile data far off (for the poles) which adds visual noise
• The fog disappears when the zoom level is in the middle of the transition between globe <-> flat, calling attention to the transition and making it hard to cover up with atmosphere effects

Would it be possible to retain the globe curvature at higher zooms whenever the camera is tilted?

Middle of globe <-> flat transition, fog is gone

Fog returns, but you can still see very far off on flat plane when camera is tilted
