01/18/97 ------------------------------------------- HF-Lab 086 beta

11/29/96 ------------------------------------------- HF-Lab 085 beta

-DEC Alpha patches from Neil Schellenberger <nschelle@crosskeys.com>

-Upgraded png libraries to PNG 0.89c and ZLIB 1.0.4 

-Added "tic" and "toc" commands for timing benchmarks

5/6/96 -------------------------------------------- HF-Lab 0.84 beta 

-PNG format writing (greyscale, 1..16 significant bits) and reading
	(greyscale, RGB, and palette, although not with alpha)

-RAW triangle format writing (ASCII). Terribly inefficient in disk space,
	but does permit subsequent export to DXF etc.

-POT format now also has variable number of significant bits (but PNG
	files are always smaller)
