[PATCH 0/1] MR6698: wined3d: Check that format_id is >= 0 before assuming it's an index.

[Rémi Bernon]

Some FOURCC values such as 0xdeadbeef will en up being negative when cast to the
enum type, and may cause a random crash later on. This happens randomly in the
ddraw tests, depending on the compiler being used.
