That sounds like a reasonable plan.

Not sure about this, on my machine the new surface works reasonable 
fast, although resize is a bit slower then before. But it may be 
different for other machines. We could, as long as we still have the 
code for XWindowBuffer in place, make this a runtime option?

How does the interaction between GNUstep and X work without knowing the 
style offset? I think we needed that to position windows correctly. I 
will have a look at your branch soon.
