[WebGL] Contexts are not updated when display configuration changed.

[Per Arne Vollan]

Calling CGDisplayRegisterReconfigurationCallback in GraphicsContext3DManager::addContext returns kCGErrorSuccess when WindowServer access is blocked in the WebContent process, but the callback function is never called. We should register the callback function in the UI process, and send a message to the WebContent process when the display configuration changed.

Looks like a good change. r=me (but please confirm EWS is happy).

Do we need to prefix this with WebCore when building in WebCore? Or is this header accessed outside WebCore?

> Source/WebCore/platform/graphics/GraphicsContext3DManager.h:71
> +

Please remove this whitespace-only change.

Is there a radar associated with this?

Yes, this file is now accessed from WebKit.

Will do. I will also create a radar.

I think this should just be "#include "Timer".
