drawn and with what color. Thus they are should be seen as mandatory when
one implements a new custom widgets via <code><a href="Graphics-UI-Gtk-Misc-DrawingArea.html#t:DrawingArea">DrawingArea</a></code>. Although the
parameterized drawing function don't have to be used, it is strongly
advisable (and more robust) to make use of the predefined graphics contexts
for the different states of a widget (retrieved by
