    canvas-container: fix warning of possible non handled value in switch
    
    We added a new enum value, but we didn't handled it on places where
    we knew it couldn't be reached. However that spits out a warning with
    gcc even if we handled it after the switch.
    
    Fix that handling a "default" and returning a default value.
