Description Matt Woodrow 2022-12-12 14:35:25 PST

ImageBuffers can be RemoteImageBufferProxy instances that are only safe to use on the thread they were created on.

We want to be able to transfer the reference to a new thread, so this adds SerializedImageBuffer to represent the state where we're currently transferring between threads.
