Subject: [PATCH] Fix compile on early Apple platforms. I think this may be
 related to the VectorSource check-in. The error is:

algparam.h: In constructor 'ConstByteArrayParameter::ConstByteArrayParameter(const T&, bool) [with T = std::vector<byte, std::allocator<byte> >]':
filters.h:1444:   instantiated from here
algparam.h:56: error: 'const class std::vector<byte, std::allocator<byte> >' has no member named 'data'
