I'll need these two entries to be communicated as well.

So far I've been cargo-culting them to the .mojom and .typemap files, but this
has not succeeded.

Is there documentation about what exactly we're supposed to do to semi-convert
these things to mojo?

Will I need to add mojo support for gfx::ColorSpace?

Is there an example of how to add private enum support to mojo?

   out->id_ = data.id();
 
   mojo::StringDataView view;
