The css3-images module is at candidate recommendation.
One property from that module that is not yet implementes in WebKit is image-resolution.
I propose to introduce the property, initially behind a runtime feature flag.
Advertised on webkit-dev:
On bug 85457, unable to build support for a runtime feature flag.
Will opt for compile time flag instead.
Nobody to fix it?
This was updated to https://www.w3.org/TR/css-images-3/.
'image-resolution' was deferred to CSS Images Module Level 4.
Some initial work was done in Bug 85264.
