================================================================================
================================================================================
Protocol for vtkvis render server.  

Commands take the general form of command and arguments using Tcl syntax and are 
terminated by a newline.  Some command arguments expect a Tcl list which can be
sent by enclosing the list in curly braces to prevent the interpreter from 
splitting the list into multiple arguments.  Likewise, strings with spaces 
should be quoted or enclosed in curly braces.  In the documentation below,
arguments are indicated by angle brackets and optional arguments are surrounded
by question marks -- the brackets and question marks are not part of the
protocol and should not be included in argument strings.  The arguments shown 
in angle brackets should be replaced with a string (where there are fixed 
choices this document indicates valid values by separating them with pipe 
symbols), a list in Tcl syntax, or a numeric value.  Boolean arguments can take
the form of 0|1, true|false, or yes|no.  Since the protocol commands are 
executed in a Tcl interpreter, Tcl code such as math expressions in expr 
commands enclosed in square brackets are also allowed.  Since the interpreter
is a "safe" interpreter, some Tcl commands that could cause security issues may 
not be available for use.

When binary data is to be sent, it should follow the newline after a command 
that indicates incoming data including a byte count argument.

axis visible <axis> <bool>
     <axis> = x|y|z|all
     Note: 'all' means all enabled axes.  To force all axes on, set each axis on

     the individual axes are enabled based on the dataset bounds.

       resets to default.

        Use pixel for image camera mode
dataset maprange <val> <?min?> <?max?> <?fieldName?> <?fieldType?> <?numComp?> <?component?>
        Controls if data range for colormapping and contours is based on
        cumulative range of all datasets ("all"), only visible datasets
        ("visible") or each individual dataset ("separate").  Defaults to
        "all"
        <val> = all|explicit|visible|separate
        The following arguments are only used for 'explicit' mode:
        <min>,<max> = Required in explicit mode, specify the range to use
        <fieldName> = Required in explicit mode, specify the field to which the
        range should be applied

       (title may be left blank)
       <legendType> = scalar|vmag|vx|vy|vz
       <numLabels> Can be zero or more 'tick' value labels
       If datasetName is omitted, the cumulative data range of all data sets 
       will be used to label the legend -- otherwise, the current setting of 
       'dataset maprange' will be used to determine if the individual dataset
       range or cumulative range will be used.

renderer clipplane <axis> <ratio> <direction>
         Set a user clipping plane, ratio is [0,1] and is always interpreted as
         0 = min_bound, 1 = max_bound, regardless of direction.  Sign of 
         direction determines normal of clipping plane.  User clip planes do not
         apply if camera mode is image.

         Set use of depth peeling algorithm for transparency

         Toggle use of two-sided lighting (controls if backfaces are lit with a
