	* Added warning for images with dimensions d that are NOT
	multiples of 2^(floor(log2(d/15))).

	* Speedup to unepic:  In collapse_pyr, don't collapse zero
	coefficients.

	* changed scale_factor to 128: binsize=0 now produces something
	closer to perfect reconstruction

Tue Oct 10 15:22:13 1995  Eero Simoncelli  (eero@tarpon.cis.upenn.edu)

	* Changed test_image to be a PGM file.
	* Version 1.1 tarfile made

Sun Oct  8 15:22:57 1995  Eero Simoncelli  (eero@tarpon.cis.upenn.edu)

	* NON-SQUARE IMAGES ARE NOW HANDLED 
	  (added butch@grip.cis.upenn.edu's mods to collapse_pyr).
	* PGM FILES ARE NOW READ (BUT NOT WRITTEN)
	  (added butch's mods for reading PGM images).
	* Slight mods to makefile: use $*.c instead of $< for denoting target

Tue Sep 19 18:40:57 1995  Eero Simoncelli  (eero@tarpon.cis.upenn.edu)

	* New file "USAGE" gives usage.
	* quantize.c: minimal binsize is now set based on the maximum abs
	  value of pixels, rather than the range.

Mon Jun  7 20:25:07 1993  Eero Simoncelli  (eero@tarpon.cis.upenn.edu)

	* Minor change: fixed up some error messages.
	* Added new internal_tranpose and internal_int_transpose that
	perform in-place transpose on non-square matrices.  This removes
	all dependencies on square images except for collapse_pyr, which
	needs to be rewritten.
	
July 1989  Eero Simoncelli  (eero@whitechapel.media.mit.edu)
	* Original source code released.
