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