The droid rules I posted recently are an example on how fontconfig can
compose separate font files in a single font face from the application
POV. Therefore I don't think a new layer is needed, but the composing
engine in fontconfig is clearly struggling to compose real-world font
files, which overlap and are not nicely broken in separate script blocks
