am 18d79267: Check that the parcel contained the expected amount of region data. DO NOT MERGE

    android::Parcel* p = android::parcelForJavaObject(env, parcel);

    const size_t size = p->readInt32();

    const void* regionData = p->readInplace(size);

    if (regionData == NULL) {

        return NULL;

    }

    SkRegion* region = new SkRegion;

    size_t size = p->readInt32();

    region->readFromMemory(p->readInplace(size), size);

    region->readFromMemory(regionData, size);

    return region;

}
