* Take screnshots using lua function, returning screenshot number. Add screenshot endpoint.
* Change capitalization from screenShot to screenshot
* Fix screenshot filename collision bug when using multiple windows.
* 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.
* Added property for aspect ratio
* Working version with aspect ratio slider controlling the FOV, and also gets updated by a window resize.
* Created horizontal fov property / GUI control that preserves aspect ratio by adjusting vertical fov to match, and updates with window resizing.
* 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
* Add ability to position screen space renderables in 3D
* Independent face camera setting
* More intuitive local rotation
* Cleanup
* Introduce global and master rotation. Remove DisableSceneOnMaster. Revisit screenspace renderables.
