Is bbPress really loading bunch of jQuery UI files?

<script type="text/javascript" src="http://localdollars.ge/wp-includes/js/jquery/ui/jquery.ui.core.min.js?ver=1.10.3"></script>
<script type="text/javascript" src="http://localdollars.ge/wp-includes/js/jquery/ui/jquery.ui.widget.min.js?ver=1.10.3"></script>
<script type="text/javascript" src="http://localdollars.ge/wp-includes/js/jquery/ui/jquery.ui.mouse.min.js?ver=1.10.3"></script>
<script type="text/javascript" src="http://localdollars.ge/wp-includes/js/jquery/ui/jquery.ui.resizable.min.js?ver=1.10.3"></script>
<script type="text/javascript" src="http://localdollars.ge/wp-includes/js/jquery/ui/jquery.ui.draggable.min.js?ver=1.10.3"></script>
<script type="text/javascript" src="http://localdollars.ge/wp-includes/js/jquery/ui/jquery.ui.button.min.js?ver=1.10.3"></script>
<script type="text/javascript" src="http://localdollars.ge/wp-includes/js/jquery/ui/jquery.ui.position.min.js?ver=1.10.3"></script>
<script type="text/javascript" src="http://localdollars.ge/wp-includes/js/jquery/ui/jquery.ui.dialog.min.js?ver=1.10.3"></script>

I only see them loaded on bbPress boards.
Can somebody confirm this? Or do I need to continiue searching for this dependances in my theme?
Because bbPress now does not really have anything fancy and jQuery style to load so many libraries.

In fact everything is done with PHP.

If this is true, can somebody also point me to places where it uses one.
