// Note that deseralizing a layers update (RecvUpdate) can delay the receipt
// of the composite vsync message
// (CompositorBridgeParent::CompositeToTarget), since they're using the same
// thread. This can mean that compositing might start significantly late,
// but this code will still detect it as having successfully started on the
// right vsync (which is somewhat correct). We'd now have reduced time left
// in the vsync interval to finish compositing, so the chances of a missed
// frame increases. This is effectively including the RecvUpdate work as
// part of the 'compositing' phase for this metric, but it isn't included in
// COMPOSITE_TIME, and *is* included in CONTENT_FULL_PAINT_TIME.
//
// Also of note is that when the root WebRenderBridgeParent decides to
// skip a composite (due to the Renderer being busy), that won't notify
// child WebRenderBridgeParents. That failure will show up as the
// composite starting late (since it did), but it's really a fault of a
// slow composite on the previous frame, not a slow
// CONTENT_FULL_PAINT_TIME. It would be nice to have a separate bucket for
// this category (scene was ready on the next vsync, but we chose not to
// composite), but I can't find a way to locate the right child
// WebRenderBridgeParents from the root. WebRender notifies us of the
// child pipelines contained within a render, after it finishes, but I
// can't see how to query what child pipeline would have been rendered,
// when we choose to not do it.
