Bug 1573994: Update Gecko test expectations for WR SVG filters
(deleted), text/x-phabricator-request
Details

Gecko is not currently using the new SVG filter primitive support in WebRender. As we support more filter primitives, the logic determining whether or not WebRender can process a given SVG filter will become much more complex due to filter primitive subregions.

We should get filter primitive subregions implemented in WebRender and then update Gecko to use the new SVG filter path.

I'll see if I can help get this landed.

https://changes.moz.tools/team.html?grouping=monthly&teams=DOM appears to be using SVG filters that will now be supported once this lands.

Would be nice to confirm that we start handling those filters directly in WR once this lands.

I haven't accomplished anything here. I don't have the background into how the clip rects work in WebRender. Dependency Bug 1573657 is unassigned. Whoever takes that on should take this one, too.
