feature -- Access

	line_join_miter: INTEGER_32 = 0
			-- A mitered join.
			-- This produces a sharp corner or a clipped corner, depending on whether the length of the miter exceeds the miter limit.

	line_join_bevel: INTEGER_32 = 1
			-- A beveled join.
			-- This produces a diagonal corner.

	line_join_round: INTEGER_32 = 2
			-- A circular join.
			-- This produces a smooth, circular arc between the lines.

	line_join_miter_clipped: INTEGER_32 = 3
			-- A mitered join.
			-- This produces a sharp corner or a beveled corner, depending on whether the length of the miter exceeds the miter limit.

feature -- Status report

			-- Is value `join` a valid line join?
