`x-show-tip' is an internal function because it exposes dangerous
features to Lisp.

If the `frame' parameter is an invisible frame, the tooltip will be
displayed unpredictably by different window managers.

There are also some things you can put in `params' that will make Emacs
crash, but I don't remember which.
