* Physically-based star rendering.
* New Tully Pic Galaxies speck file w/o Milky Way
* Removed PSC from stars rendering.
* Avoiding extra calculations during shading.
* Removed bug in billboard maximum size code.
* New method to get the current viewport resolution. Used e.g. when rendering stereo side-by-side configuration.
* Same as stereo stars.
* Improved configuration.
* Stars camera orientation.
* Separated changes in billboards.
* Adde min size control.
* Setting minimum size.
* Changed eye position. Changed data array nome inside shaders to a more accurate representation of the data.
* Billboards reflecting actual stars sizes.
* Scaling stars size based on luminosity, Abs Mag and size.
* Rendering to a texture instead of fragment calculation for each star.
* Added default parameters, new configurations and updated parameters.
* Updated speck file handling to reflect a more general specification.
* Added apparent magnitude from the speck files.
* Set correct star values values for Apogee and Galah
* Changed position from vec4 to vec3 to save GPU memory.
* 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
