1: Do the same as we do with nonpow 2 and scale the texture, (any texture ops would require the texture to be scaled which is potentially slow)
2: Set the texture to the maxium size (bad idea)
2: Set the texture to the maximum size (bad idea)
3: WARN and return WINED3DERR_NOTAVAILABLE;
4: Create the surface, but allow it to be used only for DirectDraw Blts. Some apps(e.g. Swat 3) create textures with a Height of 16 and a Width > 3000 and blt 16x16 letter areas from them to the render target.
