- it fixes how objects very close and very far are displayed in Sweet Home 3D.
- it also fixes how sky texture are displayed in the 3D view, in such a way it now shows the same image in SunFlow rendering engine, as (logically) requested here. Compared to previous versions, this fix will display sky textures a little differently in the 3D view, and I hope you won't mind this change.
Okh and ndorigatti, I hope you'll be able to test .obj modifications to handle openings. Don't hesitate to request some help.
