Feature request: render and defer

[jocelyn-stericker]

Consider a component with an image of a good dog and a refresh button. Clicking refresh enters a pending state (maybe a dog fact?) while fetching another good dog image, then switches to that image.

UpdateAction::Defer and UpdateAction::Render are currently mutually exclusive. Would an UpdateAction::RenderAndDefer or something make sense for the above scenario?

I'd say it makes a lot of sense.
