[D3D] Final DungeonSiege fixes...

(re)Hi all,

After finding out that texture parameters are per-texture objects in GL and
global in D3D, this patch fixes the last graphical glitches in DungeonSiege.

Now I just need to find how to fix the lock-up at the beginning without my
hack and the demo is fully playable (no idea about the retail version
though).

Changelog:
 - fix texture parameters handling on texture change

                 Lionel


PS: I hope you are not all fed up / lost by all the patches :-)
