            Description

            OptionalContentState keeps track of the visibility state as the PDF document is traversed. It considers content visible if the top of the element of the OptionalContent stack is visible. I believe this is not the correct way to handle this. Instead isVisible should return the logical 'and' of the visibility state of all elements in the stack.

            The attached patch resolves this issue. Additionally it resolves a thread-safety issue related to OptionalContentState.
