Jon, please don't be getting frustrated but I don't think that just 
abondoning Xorg and moving over to Xegl is a viable alternative. 
Trust me, personally, I'd consider working on Xegl much more fun, but I 
don't think we can expect from the users that they will start switching 
anytime in the near future. It will take a while. So lets do it 
incrementally. There's just lots and lots of things to do.
XVideo support being one of them (and yes, using TMU's or front-end 
scalers makes a lot of sense there, but I'd still like to see us use 
back-end scaler, for example for DVD playback but it will be very 
problematic. And quite frankly I didn't even have quite the time to 
look into YUV surfaces in Glitz but I hope Matthias can get those 
working soon :) ). 
What I'm saying is that there's is a lot of subtle issues there. Lets 
give our users and distributions something that actually works well for 
the next few months while the longterm solution is still being hacked 
on.

Yes, I'll definitely get on it as soon as I can.
