On page 96 of the Sunview Programmer's Guide (Revision A of 15/10/86) a
routine for drawing a solid or textured line between two points with a
"brush" of a specified width is described:

pw_line(pw, x0, y0, x1, y1, brush, tex, op)
	Pixwin			*pw;
	int			x0, y0, x1, y1;
	struct pr_brush		*brush;
	struct pr_texture	*tex;

Question:

Does this routine function? And if so, can anyone provide an example of a
brush and a texture?

Thanks in advance,	Alastair Horn
