--- Comment #33 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
rats.  i just realised, the dynamic shifting idea isn't going to work.  the
problem is that the atan table value may be small, whilst the x/y large, *or
vice versa*.

so this needs large shifters and complex logic, i dont think its worth it.
