The usage of `originalLength` is a bit too magical here. It needs to be easier for the next dev to figure out this code. I'm thinking of something like:

```
        // If function was auto-corrected, then originalString && originalLength hold the original function,
        // and an informational message need to be shown
        var show = (bezierCurve.originalLength ? true : false);
        if (show) {
            TimingFunctionUtils.showHideHint(this, true, bezierCurve.originalString, "cubic-bezier(" + this._cubicBezierCoords.join(", ") + ")");
        } else {
            TimingFunctionUtils.showHideHint(this, false);
        }
```

This also has the benefit of only building and passing the display strings in the correction case (which is not the usual case).
