I'm not sure exactly what I think of all this surface transform passing. I'll get back to that once I get a chance to think about it. Part of the problem is that you don't want to try and make your animations subpixel-perfect because that would require a lot of round-trips to make it right.
One thing I did want to point out though regards the details of subpixel rendering. Right now the window has no knowledge at all of where it sits on the screen. While I think this is a great idea it throws subpixel rendering off on some displays. I was reading up on it last night and, on some panels, the client would need to know its position at least modulo 2 or 4 in order to render correctly. For completely uniform subpixel layouts, it doesn't need to know this. However, some of the more clever pixel layouts are not uniform but rather have a pattern and where the buffer sits in that pattern is essential for proper subpixel rendering.
