Camera sinks under terrain

[andrzejfigula]

Hi guys,
just found that while terrain data is loading / worker is processing, it is possible to place and control camera under terrain.

Scenario is:

1. Happens for both, WGS84 Ellipsoid and STK Terrain.
2. Move the camera (ctrl+mouse controls), after moving, quickly move it again below the ground level.

Notice that this might depend on how quickly data will load / be shown on screen. It seems to happen only when not all terrain data is already loaded.

I found that this was introduced between 1.37 and 1.38, as 1.37 works fine.

Some details:

Google Chrome Version 61.0.3163.100 (Official Build) (64-bit)
macOS Sierra 10.12.6 (16G29)
NVIDIA GeForce GT 750M 2048 MB
Intel Iris Pro 1536 MB
(I think it uses GeForce while in WebGL)

Best regards, and many thanks for making this amazing software!
Let me know if you need any further information.
Andrzej
