  Vulkan: Generate fragment shading rates with compute
  
  Generating fragment shading rates on the CPU could cause avoidable
  stalls or increased latencies due to host<->device synchronization.
  Instead generate the rates using a compute shader.
  
  Optimize foveated rendering by treating a foveated draw with focal
  points whose gainX or gainY is 0 as if it were an un-foveated draw
