  21.      An ilImageTile object is used by the global function
  22.      iiiillllCCCCoooonnnnffffiiiigggguuuurrrreeeeRRRReeeettttaaaaiiiinnnneeeeddddCCCCaaaacccchhhheeee() and by the ccccoooonnnnffffiiiigggguuuurrrreeeeRRRReeeettttaaaaiiiinnnneeeeddddCCCCaaaacccchhhheeee() method on
  23.      iiiillllIIIImmmmaaaaggggeeee to specify a sub-tile of an iiiillllIIIImmmmaaaaggggeeee.  An array of iiiillllIIIImmmmaaaaggggeeeeTTTTiiiilllleeeessss is
  24.      returned by the ggggeeeettttIIIInnnnppppuuuuttttTTTTiiiilllleeeeRRRReeeeqqqquuuuiiiirrrreeeemmmmeeeennnntttt() method of iiiillllIIIImmmmaaaaggggeeee.
  25.  
  26.      The members are:
  27.  
  28.               ilImage* img;           // image that tile corresponds to
  29.               iflTile3Dint tile;      // tile of input image
  30.               int c;                  // channel start
  31.               int nc;                 // number of channels
  32.               int* chans;             // channel list
  33.               void* oneShotID;        // identifier for 'one-shot' computations
  34.  
  35.  
  36.      If the member _o_n_e_S_h_o_t_I_D is non-NULL, then it indicates that the tile is
  37.      evaluated at most once, regardless of the number of times it is
  38.      referenced in a particular computation.  It is almost always NULL, but
  39.      should be set to non-NULL for objects such as iiiillllIIIImmmmggggSSSSttttaaaatttt, that get input
  40.      data, do a computation, and cache the results once, the first time that
  41.      it is accessed after a reset.

  44.      on how to construct an iiiillllIIIImmmmaaaaggggeeeeTTTTiiiilllleeee that describes the input tile
  45.      requirement for a given an output tile of an image.
