Subject: [PATCH] HACK: Wine DX10 and DX11 Detection.

Wine doesn't implement the NULL renderer, and tries to fallback to the
REFERENCE renderer. Which then also fails when we try to create a 1x1
DXGI_USAGE_RENDER_TARGET_OUTPUT swapchain.

Until Wine manages to get a NULL renderer working, just use the WARP
renderer instead. (Which Wine also doesn't implement and falls back to
the hardware renderer for, but at least it works properly.)
