I believe it's basically a suggestion that one replaces each `foo` or `bar` API call with a prefix, e.g. `ggl_foo`, `ggl_bar`. I expect that doing so would get one slapped (literally or figuratively?) by a judge for being a wiseass.

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()".
