Background image with retina support

[benediktdertinger]

Is it possible to add media queries for retina screens?

If I currently activate the retina option and set rwp_style($image['id'], array('retina' => true)); I can't find any css queries for min-device-pixel-ratio or min-resolution.

Is this feature integrated yet?

No that isn't possible at the moment I'm afraid.
