/me discovers the reason ouch. So the 2D engine can't deal with a microtiled surface as a source, so short of using the 3D engine to do blits etc, microtiling isn't probably going to be useful for color buffers. For texture tiling I'm going to have to with keeping two copies as with this limitation we can't copy back from VRAM a micro-tiled texture with the blitter. Again we'd have to use the 3D engine to do it.
