Position canvas on PG BABYLON.Analyser

Hello,

If use this :

var myAnalyser = new BABYLON.Analyser(scene);
BABYLON.Engine.audioEngine.connectToAnalyser(myAnalyser);
myAnalyser.drawDebugCanvas();

The frame is not positioned in the canvas :

And this causes a bug : ( connectToAnalyser is not a function )

var myAnalyser = new BABYLON.Analyser(scene);
music.connectToAnalyser(myAnalyser);
myAnalyser.drawDebugCanvas();
