[PATCH 3/3] dxgi/tests: Check that the last adapter is always WARP.

[Henri Verbeet]

From: Rémi Bernon <rbernon at codeweavers.com>

Some games specifically ignore the last adapter from the adapter list,
as it's always WARP on Windows. This makes them fail to detect GPUs
correctly on Wine, as they drop one of the reported adapters.
