This is server-specific (though I believe the MIT server does this,
meaning most others supporting multiple visuals probably do as well).

In the protocol, I find only one place where a mapping between small
integers and visual classes is listed.  The mapping given there is

     0         StaticGray
     1         GrayScale
     2         StaticColor
     3         PseudoColor
     4         TrueColor
     5         DirectColor

UTSLing indicates that this is the mapping used by the MIT server's -cc
option.  This probably should accept a string instead of a small
integer; I suspect it's just a case of nobody getting around to it.
(If it's still done this way in R5 I'll probably submit a fix...)
