| * |
| * 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). |
