=item NAME
A palette functionality test
=item FEATURES
Test the Prima palette functionality on paletted
displays. True-color displays are of no interest here.
In theory, if a Prima::Widget::palette() is initialized,
the widget is expected to produce as much solid colors
from this palette as possible.
Note the $useImages that can be set to 1 to test
multiple images representation on a single widget.
