Gets Red Faction going up to the game menu and mirrors what D3D9 does. I think I'm doing the right thing here, but please treat all my PRs as unexploded ordnance.
This was discovered while investigating a crash in IDirect3DDevice8::GetBackBuffer. Red Faction will create a IDirect3DDevice8 with BackBufferCount = 0, then call GetBackBuffer for iBackBuffer = 0, which would try to assign it on top of an out of bounds vector index.
P.S.: Apparently also fixes #79 🎉
