Tk child class that supports the themes supplied in this package
A theme can be set upon initialization or during runtime. Can be
used as a drop-in replacement for the normal Tk class. Additional
options:
- Toplevel background color: toplevel
If True, ``ThemedTk`` hooks into the Toplevel.__init__ function
to set a default window background color in the options passed.
The hook is not removed after the window is destroyed, which is by
design because creating multiple Tk instances should not be done
in the first place.
- Tk background color: background
If True, sets the background color of the Tkinter window to the
default TFrame background color specified by the theme. For a
custom background color, the ``bg`` alias can still be used.
