They have to be ot_* rather than qpdf_ot_* for compatibility. * Different enumerated types are not assignment-compatible in C++, at least with strict compiler settings * While you can do `constexpr ot_xyz = ::qpdf_ot_xyz` in QPDFObject.hh to make QPDFObject::ot_xyz work, QPDFObject::object_type_e::ot_xyz will only work if the enumerated type names are the same.
