That's not what I meant. Keep a single 'struct d2d_factory *factory' field and use it for everything. Then have enter/leave inline helpers called unconditionally, and check some factory type flag in there. Once we have 'struct d2d_factory *' pointer we don't need to go through public API to get multithreaded interface, and so on.
