/OPTIONS

   /OPTIONS=(option-list)

   Specifies the optimizations to use for this proxy server. With
   the exception of the ALL and NONE options, each option has
   a NOoption form that disables the option. To enable a small
   number of options, use a combination of the NONE and the desired
   options. For example, /OPTIONS=(NONE,IMAGE) suppresses all
   optimization with the exception of image compression. To disable
   a small number of options, use a combination of the ALL and the
   undesired options. For example, /OPTIONS=(ALL,NOIMAGE,NOGRAPHICS)
   suppresses image and graphics optimization.

   ALL           Enables all optimizations. The ALL and NONE options
                 are mutually exclusive.
   NONE          Disables all optimizations. The ALL and NONE
                 options are mutually exclusive.
   [NO]ATOMS     Enables [disables] reading of the atoms control
                 file. The NOATOMS option is mutually exclusive with
                 the /ATOMS qualifier.
   [NO]GRABCMAP  Enables [disables] color map grabbing.
   [NO]COMP      Enables [disables] stream compression.
   [NO]DELTA     Enables [disables] delta request substitutions.
   [NO]GRAPHICS  Enables [disables] reencoding of graphics requests
                 (other than image-related requests).
   [NO]IMAGE     Enables [disables] image compression.
   [NO]INTERNSC  Enables [disables] short circuiting of InternAtom
                 requests.
   [NO]LBX       Enables [disables] all LBX optimizations
                 (equivalent to [NO]ATOMS, [NO]GRABCMAP,
                 [NO]GRAPHICS, [NO]IMAGE, [NO]INTERNSC, and
                 [NO]WINATTR). The [NO]LBX option is mutually
                 exclusive with any of the options controlled by
                 [NO]LBX. The NOLBX option is mutually exclusive
                 with the /ATOMS qualifier.
   [NO]RGB       Enables [disables] color name to RGB mapping in the
                 server. The NORGB option is mutually exclusive with
                 the /RGB qualifier.
   [NO]SQUISH    Enables [disables] squishing of X events.
   [NO]TAGS      Enables [disables] use of tags.
   [NO]WINATTR   Enables [disables] GetWindowAttributes/GetGeometry
                 grouping into one round trip.
   [NO]ZEROPAD   Enables [disables] zeroing out unused pad bytes in
                 X requests, replies, and events.

   The default is /OPTIONS=ALL.
