.AS Tk_Window *class

 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.
