The function selects a pen as the active drawing
object of the actual device context. A pen is used to draw
lines and curves. I.e. if you draw a single line the pen is
used. If you draw an rectangle the pen is used to draw the
borders, while the brush is used to fill the shape. If you
haven't selected a pen before drawing shapes, the shape won't
be outlined.
