[PATCH 2/6] wined3d: Minimize device windows on focus loss (v3).

Hash: SHA1

The attached archives contains follow-up patches that implement resolution changes and add tests for CreateAdditionalSwapchain.

I expect that many more small fixes will be needed for some games, similar in nature to patch 19. There are also problems in some window managers (read: those forked from Metacity)for which I haven't filed bugs yet.
