Visual distortion after changing side view settings

[Joern Ungermann]

When changing side view settings the flight path zooms seemingly to the beginning before being displaced properly.

[Reimar Bauer]

Removed wrong limitation of x-axis of 0-10.

This is never necessary as there is a proper limit being set in a second set with the alway available flight path with a length of at least two.

Fix issue #464
