Ricardo Quesada edafe726cc fix: reverse iterator on events + doesn't use additionalTransform
use reverse Camera iterator when traversing events (of course).
but somehow `setAdditionalTransform()` breaks
`setNodeToParentTransform()`. And since `setAdditionalTransform` is not
needed, we just don't use it.
