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