xcb: Speed-up image scrolling
Prevent image scrolling on client-side whenever possible - do it on
server-side. When using shared memory use server-side pixmap for
scrolled contents.
Put new image which will be scrolled to the server-side pixmap and do
scroll on it. Then do a server-side copy of a scrolled area from pixmap
to he window. Also put non-scrolled image directly to the window.
When not using shared memory also don't do redundand client-side image
scrolling.
When using OpenGL compositing first copy scrolled image area from/to
server-side pixmap.
