Effect: Draw the "color" column of a legend entry. The color

For charts, the sample is a line of the correct style,
color, and width. Since we are using wide lines,
the round endcaps of the lines will breach the column.
Therefore we need to set the clip region. We could
remove this clipping if we find a way to change the
end cap design.
For alerts, the sample is a small circle which echos
the design in the alert log itself.
