When true, the globe is rendered as a translucent surface.
The alpha is computed by blending Globe.material, Globe.imageryLayers, and Globe.baseColor, all of which may contain translucency, and then multiplying by GlobeTranslucency.frontFaceAlpha and GlobeTranslucency.frontFaceAlphaByDistance for front faces and GlobeTranslucency.backFaceAlpha and GlobeTranslucency.backFaceAlphaByDistance for back faces. When the camera is underground back faces and front faces are swapped, i.e. back-facing geometry is considered front facing.
Translucency is disabled by default.
