Changes in version 1.8.5:
	- various portability fixes
	- various SVG fixes and optimizations

Changes in version 1.8.4:
	- SVG renderer:
		- make graph|node|edge ids unique, particularly for multiedges
		- put graph|node|edge names in <title>...</title>
		- use some property inheritance to reduce size of output
		- fix compile errors when no zlib
		- updated DTD reference
	- GD renderer:
		- Minimal Type1 font support
			- look in {${X11BASE},${X11PREFIX}}/lib/X11/fonts/Type1
			- look for .pfa or .pfb font files based on fontname
		- run gdgen.c through dos2unix - problems with gcc on SuSE
	- fix Mac-OSX build problems:
		- improve strto[u]ll configure tests
		- add -fno-common for extern problem
		- function renamed to avoid conflicts (vis -> visibility)
		- add configure tests for search.h, malloc.h, getopt.h, errno.h
		- improve configure tests for FILE struct features
		- add configure tests for lrand48
	- add new demo graphs:
		- graphs/undirected/Heawood.dot
		- graphs/undirected/Petersen.dot
	- neato:
		- fix for -x implementation in neato (Bug 77)
		- fix spline problem (Bug 87)
		- fix some divide-by-zero problems
	- twopi:
		- fix Bug 117
		- update man pages for disconnected graphs capability
	- added arrowhead or arrowtail = tee
	- add dotneato/pack code to twopi
	- add contrib/prune to gnu build and install

Changes in version 1.8.3:
	- fixed parse error for lines starting with '#' in .dot files
	- fixed a recently introduced bug that caused failure of:
		digraph G {  {rank = same;  A -> B; B -> A } }
	- updated DOCTYPE header in SVG outputs
	- added dotneato/common/xbuf.[ch] for dynamic string handling
	  to avoid sprintf buffer overruns.
	- twopigen - handle special case of graphs with < 3 nodes.
	- neato - handle point shapes
	- added fontcolor support to svg
	- Fixed bug 109
	- Removed duplicate definitions for str[n]casecmp
	- Added missing declarations needed for Windows
