Lines look blurry on retina display

[Crayonberry]

I'm still learning pixi, so I'm not sure if I'm just doing something wrong, but when I draw simple lines using PIXI.Graphics, they look blurry on retina displays, but fine on normal displays.  Here's a quick JSFiddle for testing purposes: http://jsfiddle.net/BNLAd/

 

I've tried a few different combinations of adjusting the position of the line by 0.5, as well as the line thickness by 0.5, but nothing seems to do the trick.  Any ideas?

I'm not much into retina but what happens if you draw the line at double the thickness and then scale the canvas according to the device pixel ratio?

No luck...  I've also tried a few suggestions such as:

but it's resulting in my drawing being shrunk down (although it kinda looks crisp lol), while the rest of the canvas is still taking up the normal amount of space...  I'm not sure if I'm just doing something wrong or if PIXI is getting in the way.
