Avoid using Pickle::WriteSize(), which writes an architecture-dependent amount

of data, in drag action pickles. (The goal is to remove that method entirely.
Uses that never persist or send pickles over the network are [probably] safe,
but having the method around is waiting for accidental misuses.)
