  28  * The texture and sampler descriptors are laid out in a single global space
  29  * across all shader stages, for both simplicity of implementation and because
  30  * that seems to be how things have to be structured for border color
  31  * handling.
  32  *
  33  * Each shader stage will declare its texture/sampler count based on the last
  34  * descriptor set it uses.  At draw emit time (though it really should be
  35  * CmdBind time), we upload the descriptor sets used by each shader stage to
  36  * their stage.
