Re: [PATCH v2 0/4] MR4452: Draft: d2d1: Acquire lock before attempt to draw to device context

@hverbeet @zfigura. Thanks for the feedback. I've addressed both.

I've added two new commits:
1. adds a test for when the Factory is created single threaded (as that shouldn't block); and
2. added the optimization suggested by @hverbeet

I've also rebased and force pushed (as I removed the CodeWeaver bug references)
