icetDataReplicationGroup -- define data replication.

Bugs

IceT assumes that icetDataReplicationGroup is called with the exact  same  parameters  on  all  processes
       belonging   to   a   given   group.    Likewise,  IceT  also  assumes  that  all  processes  have  called
       icetBoundingVertices or icetBoundingBox with the exact same parameters on all processes  belonging  to  a
       given  group.  These  requirements  are not strictly enforced, but failing to do so may cause some of the
       geometry to not be rendered.

Description

IceT  has  the ability to take advantage of geometric data that is replicated among processes. If a group
       of processes share the same geometry data, then IceT will split the region of the display that  the  data
       projects onto among the processes, thereby reducing the total amount of image composition work that needs
       to be done.

       Each  group  can be declared by calling icetDataReplicationGroup and defining the group of processes that
       share the geometry with the local process. size indicates how many processes belong  to  the  group,  and
       processes  is  an  array  of  ids  of  processes that belong to the group. Each process that belongs to a
       particular group must call icetDataReplicationGroup with the exact same list of  processes  in  the  same
       order.

       You can alternately use icetDataReplicationGroupColor to select data replication groups.

       By  default,  each process belongs to a group of size one containing just the local processes (i.e. there
       is no data replication).

Errors

ICET_INVALID_VALUEprocesses does not contain the local process rank.
