Does anyone have any suggestions? I've treid to contact Arik Cohen but I couldn't find his mail and his blog was empty (I think he doesn't go there much but I sent him a message)
Edit: Ok, just got a reply from Arik Cohen, here's what he said for those who want to know:
"Nick Kramer talks about this on his blog
We had just implemented the order window as another window and used
Win32 calls for the alphablending (when the window was separate). When the window was hosted inside the app -- we used the same visual tree on a Canvas element that was animated."
ps: Arik if you get to see this, I forgot to tell you to start your blog for once! I've been there, it's empty
