There is an API for it. Not all programs have GUIs so the HIG doesn't restrict
the scope of the OS's APIs. Otherwise, one couldn't write assistive software or
userland drivers for new hardware. How do you think ControllerMate does what it
does?

In 10.4 and up, the recommended API is to use CGEventCreateMouseEvent and
CGEventPost. Before that, there was CGPostMouseEvent back to 10.0, but there are
situations where that can lock things up, so it is deprecated and not
recommended for use.
