With this commit, component only render child
components if they have different props (shallow
equality). Otherwise, we trust the reactivity
system to make sure that all impacted components
are updated
Before this commit, when defining a getter in the env passed to useSubEnv,
the value was read, losing the definition of the property.
After this commit, declaring a getter in the env works as expected:
the property stays a getter.
We re-add the possibility to validate props when dev mode is active.
No change in the API right Now. The dev mode is activated via the
configure method of App class.
