Thanks guys for discussion, it cleared things up a bit for me, and made me realised the futility of bothering to do what I'm doing with the qxl virt gpu. So I've resolved the upside-downness for TFP by flipping in the server and only doing sw rendering from that point onwards, which also solves the other problem of syncing to the hw. So I have something that works without these hacks, and wraps llvmpipe. Though I'd still like to see GLX_Y_INVERTED_EXT support, it would clean up a couple of copies for me and I might investigate that, though since I've no idea if any the compositors support it I'd probably need to look at that as well.
