Iffwriter2.c is modified from mand7.c of the mandelbrot program with
permission to use it by Robert J. Mical.

The calling program to SavePicture() should have all the definitions
included in this file and iffwriter.h.

Currently uses Lattice's file handling routines to allow writing over an
existing file. The delay at the end of the routine allows the drives to
settle before returning to the drawing routines.  Dos seems to need the time
even if the drawing routines don't.

Known bug:
     Crashes the system if write is made to a full disk.  Error handling
routines don't work in this case and I don't have any docs concerning
handling this dos message (disk full).
