DESCRIPTION
This procedure is invoked to retrieve an option from the database asso-
ciated 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.
