Comment(by jason):

 Actually, the above examples might just be due to the line width (the line
 around the disk).  Here is an example that again shows something really is
 wrong:

 {{{
 
p=line([[-1,0],[1,0]])+line([[0,-1],[0,1]],color='red')+line([[-1,-1],[1,1]],color='yellow')
 p.show(figsize=20,dpi=300)
 }}}

 Zooming in very closely shows that the red and blue lines are perfect, but
 the yellow line is shifted up or to the left or both (note the yellow
 pixels in quadrant 2, but not in quadrant 4).
