Auto-stop panorama after one loop

Question

I am using this panorama script: http://jsfiddle.net/zFft4/24/ I now have the animation/scrolling to stop at the end of the first loop.

What I would like is for the animation to stop at the END OF THE IMAGE and not to go all the way to the start position. If I hard-code right limit values I can get it to work somewhat, but because the live version uses a full-width viewport I cannot get it working when I resize the browser window.

Any help much appreciated...

This block of code:

if (settings.mode_360) {
    $(element).css('margin-left', 0);
    panorama_animate(element, elemWidth, settings);
}

Basically says - go one round and then start over again (it calls panorama_animate() again). So you need to remove the line (or comment it out):

if (settings.mode_360) {
    $(element).css('margin-left', 0);
    //panorama_animate(element, elemWidth, settings);
}

And it should do what you need. Notice that this code block exists twice in the code (lines 124 and 138).
