Use of template for the QR eyes + insert an image in center

[infuzz]

First, thank you for this so usefull lib.

As for square predefined square template, do you think you could add two others options :

• Predefined QR eyes
• image centered inclusion as a little logo for example with a little add like this :

<filter id="blurMe">
    <feGaussianBlur in="SourceGraphic" stdDeviation="10" />
</filter>
<circle cx="100" 
    cy="100" 
    r="40" 
    fill="#FFFFFF" 
    fill-opacity="1.0" 
    filter="url(#blurMe)"/>
<image xlink:href="data:image/png;base64,iVBzhL15vz+JEAAAAASUVORK5CYII=" 
    x="80" 
    y="80" 
    width="50" 
    height="50"/>

This image inclusion example give something like here

To illustrate my request , you can have a look on Unitag qr generator that provides lot of different angle template and logo inclusion.
