Sets the width that will be used when drawing lines
for all of the figure drawing operations (that is,
<code>drawLine</code>, <code>drawRectangle</code>,
<code>drawPolyline</code>, and so forth.

Note that line width of zero is used as a hint to
indicate that the fastest possible line drawing
algorithms should be used. This means that the
output may be different from line width one.
