Determines how the end of lines are drawn.
GDK_CAP_NOT_LAST
the same as GDK_CAP_BUTT for lines of non-zero width.
for zero width lines, the final point on the line will not be drawn.
GDK_CAP_BUTT
the ends of the lines are drawn squared off and extending
to the coordinates of the end point.
GDK_CAP_ROUND
the ends of the lines are drawn as semicircles with the
diameter equal to the line width and centered at the end point.
GDK_CAP_PROJECTING
the ends of the lines are drawn squared off and extending
half the width of the line beyond the end point.
