The context properties to give depend on the implementation of the context object, for the
Context it should look like this:
array(
'workspaceName' => 'live',
'currentDateTime' => new \Neos\Flow\Utility\Now(),
'dimensions' => array(),
'invisibleContentShown' => FALSE,
'removedContentShown' => FALSE,
'inaccessibleContentShown' => FALSE
)
