Possibility to add arbitrary text, or margin to the QR-Code

[lemmel]

Hi,

first thing first, thanks for the library!

Now, about the feature request, would it be possible to allow the user to add some text around the QR-Code ?
I would be interested by something looking like that:

If adding such a feature wouldn't respect the scope of the library, then a simple margin around the QR-Code would be enough, as it would allow user to add manually the text with something like this:

// var ctx = $0.getContext("2d"); //getting the canvas context in the debugger
ctx.font = "30px Arial";
ctx.fillText("Hello World", 100, 100); 

What do you think about this idea ?
