  22  * \brief Tests for VK_KHR_fragment_shading_rate
  23  * The test renders 9*9 triangles, where each triangle has one of the valid
  24  * fragment sizes ({1,2,4},{1,2,4}) (clamped to implementation limits) for
  25  * each of the pipeline shading rate and the primitive shading rate. The
  26  * fragment shader does an atomic add to a memory location to get a unique
  27  * identifier for the fragment, and outputs the primitive ID, atomic counter,
  28  * fragment size, and some other info the the color output. Then a compute
  29  * shader copies this to buffer memory, and the host verifies several
  30  * properties of the output. For example, if a sample has a particular
  31  * primitive ID and atomic value, then all other samples in the tile with
  32  * the same primitive ID should have the same atomic value.
