Would it make sense to add a ParamTraits::GetSize specialization for uint32 so
we can just do GetParamSize(s, r.start()) so we can be more consistent about
using GetParamSize() where possible?

[jam, 2016/05/11 17:57:02]

GetParamSize already works. Switched this and other places. We just haven't been
very consistent, just like with Write/Read, about when to use either.
