IffToGrob is an utility to convert IFF pictures into GROB 
IffToGrob can convert IFF pictures with more than one plan :
The created grob has all plans each one after the other but the 
dimensions which are written at the beginning the the GROB are
the REAL DIMENSIONS and not the vertical dimension * number of plan
In this way (which doesn't trouble the HP48) a HP48 program can 
detect how many plans has a grob

Template : SOURCE/A,DESTINATION,P=PLANS/N,A=ASCII/S,E=EVEN/S,
           I=INTERLEAVED

If destination is not specified, the grob will be saved under the name
of the source without its eventual expression and with the extension .gro
(or .s for an ascii file)

If the number of plans is not specified, ifftogrob uses the number of
plans of the IFF file 

If keyword ASCII is present, the file will be saved in ascii
which can be used under HPAsm  (ex: include Pic.s)

In non ascii mode the grob is saved with a even number of quartet
in horizontal
But in ascii mode the number of quartet of each line can be odd
To force the number of quartet to be even , you must specifie the
keyword EVEN ( only in ascii mode)

IF the keyword INTERLEAVED is present and if there are more than
one plan, then grob will be saved with interleaved plans : 
line 1 plan 1 , line 1 plan 2 , ... , line 2 plan 1, line2 plan2 ...
