loading screen question

Hello, I found very nice svg loader which I don’t know how to integrate with the puzzle. Is it structured in different way as examples in tutorials. Here code snippet:

<svg xmlns=”http://www.w3.org/2000/svg&#8221; version=”1.1″>
<defs>
<filter id=”goo”>
<fegaussianblur in=”SourceGraphic” stddeviation=”15″ result=”blur”></fegaussianblur>
<fecolormatrix in=”blur” mode=”matrix” values=”1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 30 -10″ result=”goo”></fecolormatrix>
<feblend in=”SourceGraphic” in2=”goo”></feblend>
</filter>
</defs>
</svg>

Could anybody help with setting preloader puzzle?
