                   1 - set upper threshold                   1 - set upper threshold

-                       Lower = intens - flg/2 +                       Lower = intens - flag/2 
-                       Upper = intens + flg/2 +                       Upper = intens + flag/2

-                           starting at cursor  (uses 1 bit, sets FILL flag) +            NBITS: Number of low bits to use for mask bits (default 1) 
-        8,nbits K        - set bit mask to NBITS +            MASK:  Bit mask for sampling high data bits (default is -NBITS-1 ) 
-        8,min,max K      - adjust filled voxels, starting at cursor+            FLG: 1 - adjust brightness scale and threshold values 
 +                 2 - shift if necessary, but otherwise don't clear low bits 
 +               010 - set 1 bit for all voxels where MASK value is non-zero 
 +               020 - set 2 bit for all voxels where MASK value is non-zero

 +        7,flg,fillval,datamask,low,high K       convert threshold to bit mask 
 +            FLG: 1-6 - same as 2K values 
 +                 010 - clear low bits before setting mask 
 +                 020 - use 2 bits for mask 
 +        8,nbits,flg K    - set bit mask to NBITS 
 +                 FLG  0 - simply set io->maskbits to nbits (default) 
 +                      1 - create mask of NBITS (shift data values if nec.) 
 +                      2 - clear maskbits (before setting ON if FLG&1)
