In this version, I extended the interface to Povray. It is now possible to plot curves.
Moreover, the interface can produce text objects now. It is also possible to plot wire nets just as in plot3d() with wire=true.
These objects can be mixed with other 3D objects in Povray.
The spell checker of Euler got a German dictionary. It also changed its behavior. It is now a state, not an action. The spell checker of the included Java Editor also got an update. It shows the spelling errors in comments of Euler functions now.
