Global updates

Note, unlike StoreUpdate, this doesn’t have a “Replaced” event to represent a global being added after it’s removed. This is because the global IDs are entirely controlled by the compositor, and the compositor should avoid reusing global IDs anyway, to avoid race condition with the client. So we could assume ID reuse doesn’t happen within a comfortably long time frame, which should be long enough for event listeners to handle their events.

Variants

Added(u32, Rc<G>)

A global was added.

Removed(u32)

A global was removed.
