1338424 - Consider enabling -webkit-{min,max}-device-pixel-ratio

Status: RESOLVED DUPLICATE of bug 1444139

(Core :: CSS Parsing and Computation, defect, P3)

Description

[Xidorn Quan [:xidorn] UTC+10]

It was implemented but later disabled in bug 1237720. We should re-evaluate this and probably try enabling it again.

Enabling the somehow standardized media query could give us a chance to unship the corresponding moz-prefixed media query.

If we enable -webkit-{min,max}-device-pixel-ratio, we won't need to implement the moz-prefixed media query for Stylo.

Found this bug since I was tired of seeing blurry icons on Google properties (Firefox Nightly on a 2ppx mac).
I expected better results after turning layout.css.prefixes.device-pixel-ratio-webkit on, but I got:

- GMail: no visible change, half the icons are still blurry.
- Google Docs (text document): many toolbar icons break as described in bug 1237720.

Looks like the situation hasn’t changed much.
I don’t know if there are other high profile sites which would benefit from having layout.css.prefixes.device-pixel-ratio-webkit=true.

Untracking from stylo, since we've implemented all media query features Gecko supports.

Just found this bug report -- duping forward to bug 1444139, where I've got a patch to re-enable this feature.
