Some UI elements appear fuzzy on a Retina display

[avendael]

Here's a screenshot of how the ~ at the gutter and the powerline waves look like on a Retina screen:

It would be nice if they also appear sharp on a retina screen.

I add the challenge label because to my knowledge it is not something trivial to achieve.
One possibility would be to add the support of patched fonts for the powerline.

The power line waves are fuzzy even on my non-retina Air.

With this in your .spacemacs you can avoid the waves (I think this is a much better fit with Emacs' square aesthetic anyways):

;; To avoid pixellated powerline
(setq powerline-default-separator nil)

I close this issue since it is likely to be not fixable at the spacemacs level. I added a FAQ in the README for it: d19ab5f

@person808 This screenshot looks pretty nice, how could you make this? Thank you.

Yeah, I don't like waves on retina as well. That's why I use utf-8 separator:

(setq powerline-default-separator 'utf-8)

P. S. ~ in gutter are ugly as well :(

@d12frosted Thanks for your advice, it looks better now. But person808's separator looks fancy and clear.
@syl20bnr Do you have any idea?
