  Re-land "Refactor texture function handling in OutputHLSL"
  
  This change is pure refactoring, it does not introduce any functional
  changes.
  
  Separate texture function output into a helper class and further into
  different helper functions to make the code more maintainable.
  
  Some of the logic is simplified slightly by eliminating duplicate
  cases and limiting the scope of variables where possible, but care
  has been taken to preserve the exact same functionality as before.
  
  Re-land with a fix to typo in include guard.
