16 * This bench measures the rendering time of a gridof patches.
17 * This bench also tests the different combination of optional parameters for the function
18 * (passing texture coordinates and colors, only textures coordinates, only colors or none).
19 * Finally, it also has 3 possible sizes small, medium and big to test if the size of the patches
20 * in the grid affects time.
