Thus far we've been getting the gecko+webrender integration work stood up in github, in jrmuizel's Gecko-WebRenderer branch. However we are now migrating that code to the project branch at https://hg.mozilla.org/projects/graphics. As the stuff on github has undergone a lot of churn, it doesn't make sense to reland each commit from there onto the graphics branch. Instead I will squash and re-split that work into a few logical changesets. I'm filing this bug so I have a bug number to go with those changesets.

Try push with the cleaned up patches: [1]. This is rebased on current m-c, which doesn't yet include the fix for bug 1316931. These patches do, however, remove the workaround for bug 1316931 which means if used as-is with webrender enabled, you'll get a startup crash on Windows. Non-WR builds should be fine though.
