RADMOD update:				5/18/89

MAJOR:
> ability to write files with 1024 cells (used to be 256).
> handles merging of files with different palettes.
> TARGA conversion produces a lot better results (better color reduction).
MINOR:
> cell chooser list function now displays "DONE" by cells already operated on
  (in case you forgot what you were doing).
> "destination cell #" (MOVE option question) now has a default reply (which is
  1st cell number after the last one in the output file).
> the  program no longer terminates if you enter "x" to cell chooser without 
  having selected any cells (it simply goes back to the menu).
-------------------------------------------------------------------------
> Writing files with 1024 or 256 cells:
  The default output rad size is 256 cells, since this takes a lot less disk 
space.  If you want to have the output rad size be 1024 cells, either
-- use the OUTT (change output type) menu option and enter RADB (for RAD BIG) OR
-- start with a source RAD file that has 1024 cells.
If your output RAD file size is 256 and you try to write higher cells, you're
outta luck.

> Merging files with different palettes:
  This is a real messy situation.  When you're combining several RAD files,
(using the OPEN menu command) RADMOD will check each RAD file as you open it
to see if its palette agrees with the current palette.  If all the colors are
the same, then no problem.  Otherwise it's time for you to make a decision
about how you want to resolve this problem.  The unused palettes will be
listed on the screen.  Your options:
-- ignore new palette and use the original.
-- discard original palette and use new palette.
-- offset new palette (if there's room it can be relocated after the original 
   palette).  You simply enter the palette offset (1 to 15). The new palette
   will start at this number, and all the new pixels will be adjusted to point
   to it.
-- remap new palette to best matches in original palette and ignore sub-
   palette boundaries. Don't use this if you've got stamps that require
   the primitive 16 colors/subpalette.
-- remap new palette to best matches in original palette, but respect sub-
   palette boundaries.  This keeps colors within their original 16 color
   subpalettes.
-- try 3 things in indicated order, respecting subpalette boundaries: 
   1> remap new subpalettes to identical original subpalettes.
   2> remap new subpalettes to black (unused) original subpalettes.
   3> remap new subpalettes to closest original subpalettes. 
   This last option is the RECOMMENDED one.
   (A subpalette is a set of 16 colors, starting at color 0,16,32,48,64,80...)
