[D3D 16] Patching at 36000 feet :-)

[Lionel Ulmer <lionel.ulmer@free.fr>]

Well, just to tell people that I was able to hack during my plane trip, here
is the measly patch I was able to generate...

Changelog:
 - only handle memory allocation for non-already loaded textures
 - implement GetCaps for D3DDevice7
 
                            Lionel
