23 * \brief Utility functions and structures for texture tests.
24 *
25 * This code is originated from the modules/glshared/glsTextureTestUtil.hpp
26 * and it is tightly coupled with the GLES and Vulkan texture tests!
27 *
28 * About coordinates:
29 * + Quads consist of 2 triangles, rendered using explicit indices.
30 * + All TextureTestUtil functions and classes expect texture coordinates
31 * for quads to be specified in order (-1, -1), (-1, 1), (1, -1), (1, 1).
