line-join

Arguments: stream

Returns (or sets with setf) a symbol indicating the current style for drawing the vertices of thick polylines and polygons on stream. stream should be a cg-stream.

The possible values are:

• :round (the default): rounds off each vertex.
• :miter: extends each vertex to a single point (except where the angle is very small, which would extend the vertex unreasonably far).
• :bevel: flattens each vertex.
