The glyphs need to be generated in the backend (it's the only thing that
has access to enough information from the font), but the NSLayoutManager
needs the information to do further processing. The backend will need to
implement a few methods that do the raw glyph generation and return the
generated glyphs, and NSLayoutManager will call them and store the
glyphs (and pass them on to NSTypesetter, etc.).
