Creating a preallocated primary surface isn't allowed. Technically it's 
not impossible but what's the point of it really? Unless your app is of 
the show-one-picture-and-exit style you're going to be drawing other 
stuff to your primary surface as well. That means you're going to 
overwrite the contents anyway. Also there would always be at least one 
system->video blit (it would happend when you call Flip()).
