#181 Problem with change in undocumented variable functionality in tooltip 1.5.

[Stuart Cassoff]

Undocumented variable functionality changed in tooltip 1.5.

Here is a patch that works with and without the presence of the tooltip package
and should work as well for versions of tooltip prior to 1.5.
