[PATCH] d3drm: CreateDevice is unimplemented on Windows.

[Henri Verbeet]

For what it's worth, it's not entirely unheard of for early versions
of DirectDraw to have exports/interfaces that are simply
unimplemented. It also looks that when these were originally
implemented in 2012 (commit f018a861377edb96fecc7df644e04b0e9499897e),
the main purpose was to introduce the various IDirect3DRMDevice stubs,
and not so much CreateDevice() itself.
