See https://testbot.winehq.org/JobDetails.pl?Key=68471 .
In short,
 - Creating a device returns D3DERR_SURFACENOTINVIDMEM,
 - Setting as a render target returns D3D_OK.

However, the latter case is failed with DDERR_INVALIDPARAMS on Ryzen PC,
AMD Radeon(TM) Vega 11 Graphics.

I also tested rendering target case in test_edge_antialiasing_blending().
It crashes after BeginScene() on Intel(R) HD Graphics 520, but on
testbots it doesn't.

I'll improve the test based on these knowledge. Thanks for your comment.
