add Leon's gradient to p3 GM

Browse Source 
Running...

  $ ninja -C out dm
  $ out/dm -m p3 --config 8888 srgb f16 esrgb p3 glp3 glesrgb glf16 -w foo
  $ open foo/*/gm/p3.png

... looks like esrgb and f16 are marked wrong, and all others right,
which points to a problem specific to the software backend.
