The WebContent process should not use NSScreen in the screenDepth implementation.

[Per Arne Vollan]

NSScreen method calls should be done in the UIProcess, since these calls will communicate with the WindowServer.

This patch looks good, but I think it would be better if you got rid of the duplicated code. Can you please revise that?

> Source/WebCore/platform/mac/PlatformScreenMac.mm:140
> +        return screenProperties().get(iter->key).screenDepth;

This snippet of logic is also in 'screenRect' and 'screenAvailableRect', (and perhaps others?). Can you encapsulate it in a common function that returns the appropriate screenProperties, then each of these methods can just return the member we are interested in?

Also: Should we ASSERT if the depth is zero, just in case the IPC didn't happen for some reason?
