Not working with new fabricjs

Hi
I had the same problem and I traced it to Tint filter which is no longer a standalone filter but a mode of BlendColor filter. I think it will work if you replace this routine

changeColor: function(color) {
      this.color = color;
      this.brush.filters[0] = new fabric.Image.filters.Tint({ color: color });
      this.brush.applyFilters(this.canvas.renderAll.bind(this.canvas));
    }, 

with this routine.

    changeColor: function(color) {
      this.color = color;
      this.brush.filters[0] = new fabric.Image.filters.BlendColor({ color: color, alpha: 1, mode: 'tint' });  
      this.brush.applyFilters();	
    },

I haven't extensively tested it, but it works in this fiddle https://jsfiddle.net/sfzj6t7h/
