Curved movement

Describe the bug of the extension

The easing functions "easeInBack" and "swingFrom" cause TweenPathMovement to never finish its movement. This means the Finished to move and Reached an end conditions never return true. The output of behavior.Progress() stops at 0.9999999999999998.

Steps to reproduce

1. Clone MRP from https://github.com/Granshmeyr/GDevelop-CurvedMovement-MRP
2. Run game
3. Read the screen and scroll to "easeInBack" & "swingFrom"
4. Notice how the square never turns green for these easing functions

Additional context

Temporary solution is to evaluate the expression Math.abs(pathBehavior.Progress() - 1) <= Number.EPSILON or something similar to eliminate the obvious floating point error.
