\brief A plot item, which displays a zone
A horizontal zone highlights an interval of the y axis - a vertical
zone an interval of the x axis - and is unbounded in the opposite direction.
It is filled with a brush and its border lines are optionally displayed with a pen.
\note For displaying an area that is bounded for x and y coordinates
use QwtPlotShapeItem
