  Require all PLS formats to consume exactly 4 bytes of storage
  
  D3D 11.0 UAVs only support R32_FLOAT, R32_UINT, R32_SINT formats.
  
  EXT_shader_pixel_local_storage explicitly states that all PLS variables
  consume exactly 4 bytes.
  
  ESSL images can only have both read and write access if their format is
  r32f, r32i, r32ui. (We were able to circumvent this via aliasing, but it
  was a huge source of bugs.)
  
  There is a large precedent for only supporting 4 bytes of storage in the
  capabilities we use for PLS, so this CL removes support for all PLS
  storage formats that are not 4 bytes. It also implements an "R32" mode
  for PLS, that does manual packing and unpacking of r32* image formats.
  If the application wants larger formats, it can always define multiple
  PLS planes and piece them together.
  
  Next up we ought to be able to support rg16* types with more
  packing/unpacking.
  
  With aliasing gone, and with a bit of tweaking, the PLS tests now pass
  on the Pixel 4 GLES bot.
