WebAVVideoLayer has a videoSublayer? Needs some comments so we know which layers are which.

?:0.0001 is weird, both the magic number and the ?: This needs an explanatory comment.

Do you want to explicitly end the transaction after setting the properties?

I don't see WKCAContextSetFencePort anywhere. I assume this depends on other changes?

WebKit2 doesn't need to soft link with UIKit.

Not sure what to say here. This just formalized the relationship that already existed. See the change from addSublayer: to setVideoSublayer:

Added transaction begin/commit.

I removed this and moved LayerHostingContext off of WKCAContext per AVSystemInterface guidelines.

This will annoy dbates who is trying to make us build with the public SDK. You should do the platform/spi thing.

This should really go into its own spi header, but that can happen in a later commit.

No return.

No return.

No return.

dbates backed out his changes for platform/spi. So I'm removing mine also.

We normally write this as if (!animationDuration)

I get the following build error after this change (but the bots seem fine):
Source/WebKit2/Platform/mac/LayerHostingContext.mm:121:16: error: instance method '-setFencePort:' not found (return type defaults to 'id') [-Werror,-Wobjc-method-access]
    [m_context setFencePort:fencePort];

Anyone knows what I am missing?
