Comment 4 for bug 316465

Years ago, somewhere around System 4, Canvas when drawing or scaling an object with the shift key down would constrain the object to 90 or 45 degrees. So, if drawing a line with the shift key down, it would be 90, 45, or 0 degrees, etc. Other drawing packages I have used implement similar strategies. This is a really great help when trying to draw a straight line all the way across a 20" monitor.
