[D3D 50] Some hacks to please some games :-)

[Lionel Ulmer]

D3D50
Changelog:
 Added 'blt' and 'bltfast' override functions

PS: this is a bit hacky for now, but it will be fixed the day we
    'merge' both the TEXTURE and D3DDEVICE surface type in the current
    surface hierarchy instead of adding callbacks everywhere.
