Volume handle doesn't set initial position properly

[JeffreyATW]

The volume handle must be visible when its position is set, but secondTry isn't detected due to the wrong operator being used in a boolean statement:

if (!volumeSlider.is(':visible') && typeof secondTry != 'undefined') {
    volumeSlider.show();
    positionVolumeHandle(volume, true);
    volumeSlider.hide()
    return;
}

In the above code, it should check to see if typeof secondTry === 'undefined'.

I have also rounded height/width/position of the volume handle and currents - if they're not rounded, they can be seen off by a pixel at times. Also, jQuery rounds improperly upon calling .top, .width or .height inside handleVolumeMove.
