  Ban transform feedback and blend extensions with PLS
  
  Transform feedback can lead to render pass breaks in the Vulkan backend.
  
  EXT_blend_func_extended may restrict the number of draw buffers
  depending on API state, which can invalidate a PLS implementation.
  
  KHR_blend_equation_advanced does not allow multiple draw buffers, which
  is required by some PLS implementations.
