Because there used to be two traits exposing messages to the compositor, there were two kinds of messages that could be sent: 1. In-process messages from the `Constellation` 2. Cross-process messages from other parts of Servo Now these two types of messages can be unified into one type. With that done the compositor can simply keep a single `IpcReceiver` for all messages, instead of having to set up a route for the cross-process messsages. This decreases overhead of cross proceses messages a bit, but more importantly solves an issue where Servo would rely on the compositor's cross-process message route after the `Constellation` had called `ROUTER.shutdown()`. This is part of #36442. Testing: This is covered by existing WPT tests. Signed-off-by: Martin Robinson <mrobinson@igalia.com> Signed-off-by: Martin Robinson <mrobinson@igalia.com>
