The following is a code fragment I have used to test "SetLineWidth"
PicComments on both my HP Deskwriter at home and a LaserWriter at work.
It seems to produce different results based on which printer I use.
In both cases, the first two lines are drawn "correctly" (at 1 point
and .25 point thinkness, respectively).  However, on the LaserWriter,
the last line drawn is at 1 point thickness, which is how I believe
things are supposed to work.  But on the Deskwriter, the last line
is drawn at 4 points thickness.  Am I interpreting the way SetLineWidth
works incorrectly, or is there a problem in one of the printer drivers?
(I am using Rev A.01.00 of the DeskWriter driver).

	Point	**hPt;
	
	TextFont(applFont);
	MoveTo(20, 20);
	DrawString("\pThis is a test.");
	
	MoveTo(20, 40);
	LineTo(120, 40);
	MoveTo(20, 60);
	DrawString("\pThe above line should be 1 point in width.");
	
	hPt = (Point **) NewHandle(sizeof(Point));
	(**hPt).h = 4;
	(**hPt).v = 1;
	PicComment(SetLineWidth, sizeof(Point), hPt);
	MoveTo(20, 100);
	LineTo(120, 100);
	MoveTo(20, 120);
	DrawString("\pThe above line should be .25 point in width.");
	
	(**hPt).h = 1;
	(**hPt).v = 4;			/* should it be '1' or '4' ? */
	PicComment(SetLineWidth, sizeof(Point), hPt);
	MoveTo(20, 160);
	LineTo(120, 160);
	MoveTo(20, 180);
	DrawString("\pThe above line should be 1 point in width.");
