    I am trying to build an image display window which will allow me to
    show short animations by displaying a series of colour images in rapid
    sucession.

At MIT we've hacked together a server extension to support shared-memory
pixmaps (data shared between client and server), which results in a PutImage
having approximately the same performance as a CopyArea.  It doesn't work
across a network, of course, but it's basically about as fast as you can go.
We currently just consider it an experimental hack, sorry, no promises as
to if or when it will show up in public.
