Alternatively, we could optionally do lazy decodes, the way bench_pictures does.

We certainly want to do lazy decoding when timing recording (as you realized
when you wrote https://codereview.chromium.org/212563009), but maybe we don't
want lazy in other cases. Or maybe we want to do both and compare.

         if (pic->get() == NULL) {
             SkDebugf("Could not read %s as an SkPicture.\n", path);
             return false;
