bug: wrong reaction when AASetting(scaling) isn't 1

[xiazeyu]

将scaling调至大于1时，由于实际大小与显示大小不同，所以鼠标指针的跟随也会出现问题，右下角无法识别

• Solve it
• Test if mobileScaling also have problem

  // 此处获取的是canvas的大小 即绘制大小，与实际显示大小无关
  let width = canvas.width;
  let height = canvas.height;
  // 以下为实际显示大小
  // let sWidth = parseInt(canvas.style.width);
  // let sHeight = parseInt(canvas.style.height);

  deviceToScreen = new L2DMatrix44();
  deviceToScreen.multTranslate(-width / 2.0, -height / 2.0);
  deviceToScreen.multScale(2 / width, -2 / width);
