/*
* 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
* SurfaceTexture. 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();
* fc->finishFrame();
* }
*
