These two structs describe options used during printing. They are passed through numerous classes as pointer. In this case, reference semantics are preferred, as references: - can never be null - can not change during their lifetime This not only helps the compiler, as it can optimize away null checks, but also your fellow coder. Moreover, it prevents unintentional creation of uninitialized references: one can't create an instance of a class without initializing a reference member. It does not prevent references from going dangling. However, pointers have the same disadvantage. Contains a few whitespace cleanups. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
