Texture mapping and fish eye

This new version 3.058 fixes a problem that sometimes appears with OpenGL. The textures are applied on a flat surface with an annoying perspective effect. This could be seen in the program by displaying the constellations or by approaching a probe.

(The images on the left come from the 3.0.57 version, before the correction. The texture mapping is correct on the right.)


This version also corrects the aspect of the sky with the minimum zoom value, the representation of the stars is now more realistic.
