示例1: onNewPictureSnapshot

        SkBigPicture::SnapshotArray* pictList = NULL;
        if (fDrawableList) {
            // TODO: should we plumb-down the BBHFactory and recordFlags from our host
            //       PictureRecorder?
            pictList = fDrawableList->newDrawableSnapshot();
        }

        SkAutoTUnref<SkLayerInfo> saveLayerData;

        if (fBBH && fDoSaveLayerInfo) {
            saveLayerData.reset(SkNEW(SkLayerInfo));

            SkBBoxHierarchy* bbh = NULL;    // we've already computed fBBH (received in constructor)
            // TODO: update saveLayer info computation to reuse the already computed
            // bounds in 'fBBH'

        size_t subPictureBytes = 0;
        for (int i = 0; pictList && i < pictList->count(); i++) {
            subPictureBytes += SkPictureUtils::ApproximateBytesUsed(pictList->begin()[i]);
        }
        // SkBigPicture will take ownership of a ref on both fRecord and fBBH.
        // We're not willing to give up our ownership, so we must ref them for SkPicture.
        return SkNEW_ARGS(SkBigPicture, (fBounds,
                                         SkRef(fRecord.get()),
