DESCRIPTION

This procedure is invoked to retrieve an option from the database
associated with tkwin's main window. If there is an option for tkwin
that matches the given name or class, then it is returned in the form
of a Tk_Uid. If multiple options match name and class, then the
highest-priority one is returned. If no option matches, then NULL is
returned.

Tk_GetOption caches options related to tkwin so that successive calls
for the same tkwin will execute much more quickly than successive
calls for different windows.
