mm->vox integers per AFNI controller window OUTPUT

AFNI controller window OUTPUT 
------------------------------------------------
Appears to pull existing integer voxel coordinates from internal integer-based
data structures. Doesn't need conversion from float to integer.

When the AFNI controller window is set to display voxel coordinates for the
current crosshair location (GUI "Set Coord Order"->"Voxel Indexes"), it displays
integer coordinates pulled from internal integer data structures.

from afni.c :

	7224 STATUS("voxel indexes") ;
	... (skip a bunch of stuff related to visible functionals)...
	...
	7247      } else {
	7248         sprintf( buf , "index %d:\nvoxel x = %4d\nvoxel y = %4d\nvoxel z = %4d" ,
	7249                  ixyz , im3d->vinfo->i1 , im3d->vinfo->j2 , im3d->vinfo->k3  ) ;
	7250      }
