        changing the colormap is much faster than copying pixmaps.

    Unless the window manager gets in the way.  Is the mechanism in ICCCM
    fast enough for this?

Independent of ICCCM.  We're talking about changing RGB values in a
writable colormap, not installing a new colormap.  The WM does't get
involved at all.

Note that there is a proposed double-buffering extension to X, which was
out for public review this summer.  We have a (very) sample implementation
which is expected to be in R4.
