Expose measureText from canvas context

Why do you need such method? You can create Konva.Text instance. And then use width() and height() functions.

You're absolutely right, that works out perfectly. I will make sure I research the rest of the framework thoroughly before I propose a change in the future.

I want to reopen issue. Now I think this code might be useful. Currently if you want to create your own shape you have to use this:

var triangle = new Konva.Shape({
      sceneFunc: function(context) {
        context.beginPath();
        context.moveTo(20, 50);
        context.lineTo(220, 80);
        context.quadraticCurveTo(150, 100, 260, 170);
        context.closePath();
        context.fillStrokeShape(this);
      },
      fill: '#00D2FF',
      stroke: 'black',
      strokeWidth: 4
    });

context argument is not native canvas context. It is Konva wrapper. But users expect here native context (and all available methods from context). So I want to make possible to work with this wrapper in completely same way as with native context.
One more example if want to change context attributes on this function you have to write:

context.setAttr('globalCompositeOperation', 'destination-over');
// or
var nativeContext = context._context;
nativeContext .globalCompositeOperation =  'destination-over';

It is all unclear.
