Line Join Properties

Line join properties are for expressing the visual appearance of what happens when line segments meet. They can be round, beveled, or mitered. Notice the corners of the following rectangles, which illustrate the effect line join properties have.

The only attribute of line join properties is @lim. This attribute limits the amount by which lines can be extended to form a join. Normally, this is a relatively infrequent occurrence, but in the case of nearly parallel lines, this attribute comes into play.
