Fix boot animation rotation problem when ro.sf.hwrotation is set to 90 or 270

    if (!frame.isValid()) {

        // the destination frame can be invalid if it has never been set,

        // in that case we assume the whole display frame.

        char value[PROPERTY_VALUE_MAX];

        property_get("ro.sf.hwrotation", value, "0");

        int additionalRot = atoi(value);

        if (additionalRot == 90 || additionalRot == 270) {

            frame = Rect(h, w);

        } else {

            frame = Rect(w, h);

        }

    }

    if (viewport.isEmpty()) {

        // viewport can be invalid if it has never been set, in that case
