Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope.
It is being used in planetarium projectors. Just set your coordinates and go.
Global switch to Qt. Don't support SDL main application anymore.
The whole StelApp class is managed by a QGraphicsScene, inside a QGraphicsView.
Removed deprecated sources from the core of stellarium (old GUI, TUI and
Continued API cleaning and simplifications.
