I would just have the printf parameters:
    al_append_log(window, const char *format, ...)

I think we should also let the user (try to) close the log window, and
generate an event when that happens.  Then examples which output usage
information can give the user a chance to read the message before
calling al_close_native_log_window().

For non-example uses, we should limit the size of the log.  Probably a
fixed limit of 1000 lines or so is good enough.
