请问这个 canvas.clipPath(mClipPath);是用来做什么的，是不是可以不要它，直接drawBitmap关于shininig图片?

private void drawIcon(Canvas canvas) {
if (isThumbUp) {
if (mClipPath != null) {
canvas.save();
canvas.clipPath(mClipPath);
canvas.drawBitmap(shining, startX + dp_2, startY, mBitmapPaint);
canvas.restore();

            //扩散的圆环
            canvas.drawCircle(startX + mCircleX, startY + mCircleY, mRadius, mCirclePaint);
        } else {//为了保险，虽然正常情况mClipPath都不会为null
            canvas.drawBitmap(shining, startX + dp_2, startY, mBitmapPaint);
        }

        canvas.drawBitmap(thumbUp, startX, startY + dp_8, mBitmapPaint);
    } else {
        canvas.drawBitmap(notThumbUp, startX, startY + dp_8, mBitmapPaint);
    }
}

这个是为了达到那个shining，散开的效果。
