Surface rotation doesn't stops if mouseup event is out of chart

[khalitovsv]

If start rotate surface chart, and mouse up outside of chart, it will continue listening mousemove events and rotating chart.

I think you need to handle mousedown event on chart object, and handle mouseup event on document.

src\surface\Chart.js

anychart.surfaceModule.Chart.prototype.handleMouseEvent = function(event) {
  if (event['type'] == acgraph.events.EventType.MOUSEUP) {
    this.mouseRotation_ = false;
  }
};
