2017 * This test fixture is for testing GL -> GL texture streaming from one thread

2020 * GLConsumer.  Additionally it supports interlocking the producer and
2021 * consumer threads so that a specific sequence of calls can be
2022 * deterministically created by the test.
2023 *

2026 * TEST_F(...) {
