My apologies for any errors.  A good friend of mine has been doing a
fair amount of X programming at MIT and uses only X10 because he said
X11 was too slow becuase of the byte/pixel reason.  Perhaps he's
wrong, perhaps the implementation he's using is brain-damaged even
though the protocol itself isn't.  Thanks for setting the record
straight.

(I guess that teaches me to try and write intelligent comments late at
night.  :-)
