Change default preview size for all sessions

[vicshar]

Currently if you change the preview size to fit image in window it will keep it for the current session. But as soon you close the program and open it again it returns to the default that is scale only if the image is bigger but not smaller. I can not change this in preferences either as there is not menu related there. Because I use normally "fit image in window" I need to set it in each new session.

Any way to keep this between sessions?

By the way the last version is fantastic, now really a lot better than the older Xnview.
