Bug 230159 – Send preference updates to the GPU Process

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Per Arne Vollan]

Like the WebContent process, the GPU process should also receive preference updates since it is blocking the preference service in the sandbox.

Oh, nice! We have centralized this now.

I wonder if there is any perf benefit to making this a "NeverDestroyed" thing, since we presumably construct this set every time we try to decode preference values.

That is a good point. I think there will be a performance benefit from this, although since this should not be a hot path, I think it also could be good to avoid the small added memory cost by making this NeverDestroyed.

Thanks for reviewing!
