* Work on timeline translations
* Add Apollo 11 Descent data
* Ability to display negative altitudes
* Expose globe translation properties
* Added timeline rotation, and some scene updates.
* Cleaning up apollo_sites scene; fixing boulder 1 in place to adress heightmap issue
* Use quaternion slerp instaet of linear interpolation + Cleanup
* Change to old lem model while waiting for new version to be pushed to data repo
* Small fixes
* Replace setCameraState with setNavigationState + equivalents
* Add documentation and verification of NavigationState-related interfaces
* Documentation and verification fixes
* Change reference frame behavior
* Scene fixes
* Replace earthrise recording with navigation state and time
* Added functionality of saving out screenshots (with fixed FPS) from a recorded session during playback.
* Test of feature to request if all data is ready to be rendered, primary used in GlobeBrowsing. Need to go over how chunkTiles are set to OK (some are never OK..).
* Estimated having working request of checking if chunks with correct level have their color and height data loaded and ready to be rendered. Will re-enable frames saving and try making a movie.
* Created adaptive LOD factor based on available/unavailable tile data (such that we don't run a lot of iterations with asking for a pile of data that does not fit in the tile cache).
* Made it able to specify tile cache size in configurastion file. Renamed other Cache value to WMSCache, as we have the TileCache as well.
* Fix for when focus node has nor renderable, when checking for if dersired data has been loaded. Should probably check all renderable/planets anyway, not just a focus object.
* Fade fixes
* Clean up RenderableSphere. Add orientation properties.
* Sane defaults for Digital Universe
* Clean up New Horizons related code
* Add basic scene
* Add ability to initialize rotation as quaternion and mat3
* Adapt legacy code to new Renderable interface
