ttttkkkk____sssseeeettttPPPPaaaalllleeeetttttttteeee tries to compute reasonable defaults for any options that
you don't specify. You can specify options other than the above ones and
Tk will change those options on widgets as well. This feature may be
useful if you are using custom widgets with additional color options.
Once it has computed the new value to use for each of the color options,
ttttkkkk____sssseeeettttPPPPaaaalllleeeetttttttteeee scans the widget hierarchy to modify the options of all
existing widgets. For each widget, it checks to see if any of the above
options is defined for the widget. If so, and if the option's current
value is the default, then the value is changed; if the option has a
value other than the default, ttttkkkk____sssseeeettttPPPPaaaalllleeeetttttttteeee will not change it. The
default for an option is the one provided by the widget ([[[[lllliiiinnnnddddeeeexxxx [[[[$$$$wwww
ccccoooonnnnffffiiiigggguuuurrrreeee $$$$ooooppppttttiiiioooonnnn]]]] 3333]]]]) unless ttttkkkk____sssseeeettttPPPPaaaalllleeeetttttttteeee has been run previously, in
which case it is the value specified in the previous invocation of
