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

- *     };
- *
- *     runProducerThread(new PT());
- *
- *     // The order of these calls will vary from test to test and may include
- *     // multiple frames and additional operations (e.g. GL rendering from the
- *     // texture).
- *     fc->waitForFrame();
- *     mST->updateTexImage();
