parseInt - rounding returns wrong value

At first, awesome piece of code...

But i've go a problem if i try to implement the toggle-buttons. When the action.translate.get.matrix - method gets called to prove the current state (left, right, close) it always returns a one pixel difference. So the state().state returns a wrong value.

my fix was to change line 176

``` javascript
return parseInt(matrix[index], 10);
```

to

``` javascript
return Math.round(matrix[index]);
```

Is that a possible fix, or will I get some other problems here?

Start at line 176 and trace the action.translate.get.matrix method used by state() to determine the left, right, or close position. Reproduce the toggle-button behavior and compare the current parseInt handling with the reported rounding behavior. Done means state() identifies each position without the one-pixel discrepancy.
