2019 * This test fixture is for testing GL -> GL texture streaming from one thread
2020 * to another.  It contains functionality to create a producer thread that will
2021 * perform GL rendering to an ANativeWindow that feeds frames to a
2022 * GLConsumer.  Additionally it supports interlocking the producer and
2023 * consumer threads so that a specific sequence of calls can be
2024 * deterministically created by the test.
2025 *
2026 * The intended usage is as follows:
2027 *
2028 * TEST_F(...) {
2029 *     class PT : public ProducerThread {
2030 *         virtual void render() {

2032 *             swapBuffers();

2034 *     };
2035 *
2036 *     runProducerThread(new PT());
2037 *
2038 *     // The order of these calls will vary from test to test and may include
2039 *     // multiple frames and additional operations (e.g. GL rendering from the
2040 *     // texture).
