                1.1 ready for version 2.
                The BaseCamelotFilter provides common functionality for both this and the
                web file filter as they are essentially the same thing.

    Author:     Mark_Neves (Xara Group Ltd) <camelotdev@xara.com>

                that will be exported.

                It's like a NULL byte sink, where no bytes are actually outputted anywhere
