Hmm.  An `FT_IS_LAYERED(face)' macro isn't really helpful.  We would
rather need `FT_IS_LAYERED(face, glyph_index)'.  I don't see much
benefit in comparison to

  if ( FT_Get_Color_Glyph_Layer( ... ) )
    ...

as we have now.

It does.

FT_LOAD_NORECURSE is for composite glyphs only.  I don't want to abuse
it for glyph layers, inspite of some similarities.  Just imagine if
you have both composite glyphs and colored glyph layers...
