We're now removing the web/ directory as part of Onion Soup 2.0. web/ will be
gone in the near future.

Would you move this file to bindings/core/v8/?

[peria, 2017/07/07 06:22:04]

Just to confirm before actually working for it.
You mean, we can use files under bindings/core/v8/ directly from 
tools/blink_v8_snapshot/? Then I prefer to use
V8ContextSnapshotUtil::TakeSnapshot() instead. Is it allowed in Onion Soup 2.0?

We should keep the public API in public/web/. We can put the implementation in
bindings/core/v8/. tools/blink_v8_snapshot/ can use the public API.

(Once Onion Soup 2.0 is done, tools/blink_v8_snapshot/ can directly use
bindings/core/v8/, but we are not yet there.)
