This is the same behaviour as for the RadioToolButton and the
ToolButton. See 5a1b380dd6 where
we did the same for the RadioToolbutton.
Updated the toolbuttons.py test to be able to test that code
path.

Draw a black background in the buttons when the palette is up, as
commit 01a06943 did with the ToolButton. As the comment for that
commit states, we can change the prelight background color in the
theme, but not when the mouse moves over the Palette.
Also add testcase to test the three toolbuttons.
