* Faster rendering for renderableOrbitalKepler
- Computes relevant vertices on CPU rather than filtering all vertices on the GPU
- Removes geometry shader for trails rendering
- Changed GUI name of RenderingMode "Points+Trails" to "Points and Trails"
Better performance for `RenderableOrbitalKepler` when running `Trails`, `Points` or `Points+Trails`.
Trails optimized by culling non-visible line strips.
Points optimized by changing a lot of calculations from double to float.
Fixes following issues: #625 , #1067 , #1212 , #1472 , #2072 , #2235, #2964
- Trails in `renderableTrailTrajectory` now goes through the spacecraft when using `AccurateTrailPositions`.
- Trail fading controls have been improved for classes using the `renderableTrail` class.
- `renderableOrbitalKepler` (asteroids/satellites) can now be rendered as both trails and points (or both at once). Solution implements similar functionality/controls as `renderablePointCloud`.
- Default setting for SweepChunking has been changed from `true` to `false` (iterative calculations of `renderableTrailTrajectory`).
- Some fixes related to missing points or off-by-one errors related to trail rendering
to avoid confusion with opacity name change. Also, the 'transparency'
used in the rings had a diffrent meaning than for the rest of the
rendered objects. It affects the filtering of the color values.
* Updating DU for new data.
* Changed how OS handles partiview colormaps.
* Multiple changes to adapt OS' behavior for cmaps.
* Small tweaks. MW sphere is now fading in the correct spacetime.
* Added all the Star Orbits.
* Fixing bug in speck reading procedure.
* Changed code to allow comments into data region of a speck file.
* Added deep sky objects.
* Added Home label
* Fixed bug in drawelements.
* Added Sun as a separated star for better control.
* Update version numbers on DU assets
* Move starorbits into their own asset file
* Making some of the digital universe renderables fully opaque for performance gains
