  Make output variables part of Program's shared data.
  
  Also initialize this structure within Program instead of DynamicHLSL.
  This should have benefits for other back-ends. Also these variables
  weren't being serialized and de-serialized with the program binary,
  which could mess up WebGL apps that use MRT.
