Bug 1547351 - Automatically set content process render root r=kats
This implements the idea of automatically setting a content proc's render root based on the render root enclosing the iframe that points to it. There was a bit of cleanup in here that was a bit tricky to extract from the core patch revolving around how we use the Api(...) helper. This was to avoid the situation where we use the Api(...) helper before our render root is initialized, when we don't actually have to. I.e., when we just want the root WebRenderAPI in all cases. An alternative to this approach could be to fully built out the WebRender transactions and just queue those up to be sent. However, transaction building has various side effects which are committed before the transaction is actually sent, so we would have to build out some scheme for deferring those as well. This seemed simpler. Patch primarily written by :dthayer Differential Revision: https://phabricator.services.mozilla.com/D37078 --HG-- extra : moz-landing-system : lando
