In zxdg_output_v1 version 3, done is deprecated and should be replaced
with wl_output.done. This makes automatically send done upon change not
suitable for the usage. OutputInterface user should now use done()
explicitly to send the update.
CCBUG: 433224
The xdg-output spec omits whether the compositor has to destroy all xdg-
output resources when the associated wl_output global is removed.
This means that no xdg-output resource should be destroyed unless the
client has called the destructor request; otherwise the client may panic
due to protocol errors.
Starting with Qt 5.15.2, it's okay to destroy generated wrapper objects
without destroying associated resources. Destructor requests will be
handled behind the scenes for inert and orphaned resources by code that
is generated by qtwaylandscanner.
BUG: 426293
Generated code typically cleans up resource objects when the client
calls the relevant destructor.
In multi-cast mode our wrapper can be deleted at any time, whilst a
client resource exists any existing resources that have a pending
message will then crash the compositor.
Deleting resources ahead of time also resolves this. calls to this
resource will no-op. The zxdg_output_v1::destroy_func will then be
called to delete the Resource object.
