In spite we have Antartica's wonderful "xepdmgr", I've always wanted to figure how how screen refresh on iLiad is managed. I thought I just figured out its rough picture and I found this thread.
Yes, I know it's an old thread, and most people won't even notice it since ipdf viewer is quite stable since FW2.11.
I post here just because I didn't know the framebuffer refresh mechanism of ipdf was developed by Scotty only after read the whole thread.
Although Scotty has abandoned his iLiad, I think what he had done is really amazing.
