The API is just a signature for calling the function -- I was joking that instead of

  screen_draw(int x, int y);

what Google could do is:

  ggl_screen_draw(int x, int y);

and say "New API -- they've got screen_draw(), we have ggl_screen_draw()".

Copyright protects deivative works, not just literal copying, so if copying the API is a violation, so is such a direct transformation.
