| Description |
Pens, used for drawing lines.
Portability notes:
- On Win32, the pen is also used to draw a line round all the filled
shapes --- so the pen color also affects how polygons, ellipses
and regions are drawn.
- On Win32, the Style is ignored (i.e. treated as Solid) for pens
of width greater than 1. This problem does not apply to X11.
