Retrieve an implementation of this render pass for the given renderer.

That supports the specified data type and the specified number of channels.

Parameters:

  [in] | renderer | The renderer
  [in] | fbType | The base data type of the frame buffer

Returns:
  A pointer to the pass implementation or null if no definition exists

Status Codes:
  - MS::kSuccess The implementation was retrieved
  - MS::kFailure An object error has occured
